2.3 Not migrated
Web scheduler tasks
Location in Plesk: Profile & Preferences
Helm 3 Type Plesk
Company Name String Company name
Address Strings Address, all address strings concatenated
Town String City
State/Country String State/Province

Mobile Tel. String Phone
Fax Tel. String Fax
Primary Email Address String E-mail
Secondary Email Address String E-mail, only if primary email is empty
3.1.2 Servers
The migration is only for single server Helm 3 installations.
3.1.3 Services
All configured services are mapped to corresponding settings in Plesk. Because specific type of service is not specified during migration it doesn’t really matter that Plesk doesn’t support some of services that Helm 3 supports. Type of service is only that matters.
Here is the list of all Helm 3 services grouped by type:
Database Microsoft Access
3.1.3.1 Service settings
In Helm 3 some settings and limits are configured on per service basis. Settings are mapped to global Plesk settings, limits are transferred to every reseller plan.
3.1.3.1.1 Web services

ISAPI FileName String Ignored
Maximum Domains Number Ignored
3.1.3.1.1.1 Shared SSL
In Helm 3 name of shared SSL domain is configured in IIS5/6 service settings. In Plesk a special domain is created during the migration under admin with the same name as in Helm, so shared SSL URLs stays unchanged after the migration process. Content of shared SSL folders is migrated automatically.
Migration administrator should transfer SSL certificate manually to the Plesk domain.
Limitation: shared SSL status for “add-on domains” (2nd and subsequent domains in a package) is not migrated. All content of SSL folders is moved to private/SSL folder in Plesk, so a site administrator may enable shared SSL using Plesk UI and move the content using Plesk File Manager.
3.1.3.1.2 Mail services
Create Default Account Toggle Ignored
Default POP3 Account String Ignored
Default Catch All? Toggle Ignored
Max. Mailbox Size Number Reseller Plan/Resources/Mailbox size and Mail Account/General/Mailbox/Mailbox size; Note: different mail services specify different units of measurement in Helm, for example it is “KB” for MailEnable or “Bytes” for IpswitchImail. This field is not supported by MerakMail, so mailboxes migrated from MerakMail service have unlimited mailbox size.

3.1.3.1.6 Statistics services
Plesk doesn’t have settings for statistics services, so all settings are ignored.
3.1.4 Resources
In Helm 3 resources group service by type and specify load-balancing settings. It is not required to do resource migration for single server installations.
3.1.5 Resellers
Helm 3’s resellers are migrated to Plesk resellers.
Note resellers in Helm 3 are unable to create their own domains.
3.1.5.1 Reseller Plans
Helm 3’s reseller plans are migrated to Plesk’s reseller plans.
Helm 3 allows selecting configured resource for every type (Web, DB, Stats, Mail, and FTP). This selection is ignored for all resources but DB – MySQL / Microsoft SQL selection is honored and controls which limits are affected in Plesk’s plan.
3.1.5.1.1 Set Up Extra Features
Plesk doesn't have counterpart for extra features specified in reseller plans (hosting plan's extra features are migrated to Plesk's addons). However, extra features purchased by resellers are migrated by creating custom per-resellers plans.
For example, if reseller R was created under reseller plan PLAN and purchased extra feature "10 domains" in quantity of 7, migrator creates reseller plan "PLAN for R" with 70 more domains and signs up reseller R to that plan.

Reseller personal details migrated the same way as admin personal details.
3.2.2 Global DNS Settings
Not migrated, see Resellers can’t add DNS templates limitation.
3.2.3 Domain Reg. Settings
Not migrated.
3.2.4 Users
Helm 3’s users are migrated to Plesk customers. In Helm 3 users are not signed up to a hosting plan, rather they create “package” for a hosting plan and then add domains to that package. In Plesk situation is close only users are called customers, and packages are called subscriptions.
3.2.5 Hosting Plans
Helm 3’s hosting plans are migrated to Plesk hosting plans.
3.2.5.1 Set Up Extra Features
Plesk's counterpart to extra feature defined at reseller level is addon. Addons are defined at reseller level (not on plan level as in Helm), so extra features from all hosting plans are gathered and migrated to reseller.
Plesk's addons have several limitations:
Addon names must be unique. o Solution: Unique name is created by adding internal addon identifier. For example, two
extra features named "Extra" will become "Extra" and "Extra #34" where 34 being the unique identifier.
Addon can be purchased only in single quantity. o Solution: For purchases in quantities other than 1 migrator creates fake addons and
purchases them once. For example, purchase of extra feature "Extra" in quantity of 11 will become purchase of extra feature "Extra x11".
Addon can be purchased only once. o Solution: For multiply purchases of same extra feature migrator creates fake addon and
purchases that addon once. For example, if feature "Extra" was purchased twice in quantities 10 and 1 migrator will create fake addon "Extra x11" and purchase that addon once.

Max Database Users Number N/A
3.3 User migration 3.3.1 Personal Details
User personal details migrated the same way as admin personal details.
3.3.2 Packages
In Helm 3 user creates packages for a reseller’s hosting plan and then adds domains to the packages. In Plesk packages are called “subscriptions”; customer can add many domains to a single subscription and can have several subscriptions.
However, there is a difference: in Plesk subscription has ‘main’ domain which is created with subscription and can’t be deleted. So there can’t be empty subscriptions.
3.3.3 Domain files
In Helm package is merely a group of domains, it exists only in Helm. Packages are migrated to Plesk’s subscriptions.
Note Shared SSL content of main domain are migrated into Plesk httpsdocs folder, SSL folders of addon domains are transfered into private/[domain name]/SSL folders.
3.3.4 Domain settings 3.3.4.1 Email accounts
Corresponding location in Plesk: Mail/E-mail Addresses.
3.3.4.1.1 Account settings
Plesk locations are relative to Email Address editing dialog for a specific account.
C:\domains\

Enable responder Toggle Auto-Reply/Switch on auto-reply
Auto Responder String Auto-Reply/Auto-reply message text
Store & Forward To String Forwarding/Forward incoming messages to the following e-mail address
3.3.4.2 Email forwarding
Email forwarders (which are called mail aliases in plan limits) are migrated to Email Address with disabled mail box (unchecked General/Mailbox).
3.3.4.3 Multi-recipient addresses
Multi-recipient addresses are migrated to Email Address with disabled mail box (unchecked General/Mailbox) and enabled forwarding to several email addresses.
3.3.4.4 FTP Accounts
Corresponding location in Plesk: Websites & Domains/FTP Access.
Helm 3 creates one predefined FTP account for each domain. Account is named after domain (e.g. “domain.tst”), mapped to the home folder, has permissions to read and write. The account is not special and can be deleted. It will be migrated as an ordinary account.
Note that in Plesk users can’t write to the domain root. See Different file system structure limitation.
3.3.4.4.1 Account properties
Password String New FTP password
Can Read From Folder Toggle Read permission
Can Write To Folder Toggle Write permission
FTP Folder String Home directory
3.3.4.5 File Manager

3.3.4.12 ColdFusion DSNs
Corresponding location in Plesk: Websites & Domains/Databases.
In both Helm 3 and Plesk databases are created under domain, and users are created under database.
Helm 3 allows creating databases of type “Microsoft Access” in addition to database type configured in package. Plesk doesn’t support Access databases.
3.3.4.14 MIME Types
3.3.4.15 Custom Error Pages
3.3.4.16 FrontPage Extensions
Not migrated. Location in Plesk: Websites & Domains/[domain]/Microsoft FrontPage support.

PHP Select Websites & Domains/[domain]/PHP support
Python Toggle Websites & Domains/[domain]/Python support
CGI-Bin Toggle Websites & Domains/[domain]/CGI support, interesting thing is that in Helm 3 ‘cgi-bin’ folder is an ordinary folder while in Plesk it is an application.
ColdFusion Toggle Websites & Domains/[domain]/ColdFusion support, requires ColdFusion component to be installed.
3.3.4.20 Statistics
In Helm 3 Statistics page shows current usage statistics and also allows to enable/disable advanced statistics generated using either AWStats or Webalizer.
In Plesk Website & Domains\Web Statistics shows the current statistics, and Website & Domains\[domain]\Web statistics allows to enable/disable AWStats or Webalizer.
4 Limitations
Virtual directories don’t support URL redirection
All domains in a subscription share one IP
Forwarding domain limitations
Only one ASP.NET/ PHP version is configured in Hosting Plan
Some hosting plan limits are migrated to toggles
Some plan limits are not migrated
No alternative to “Multi-Recipient Addresses”
Different file system structure
Exotic ODBC DSN types
Undeletable domain in subscription
4.1 Resellers can’t add DNS templates
In Helm 3 both admin and resellers are able to add entries to “Global DNS Settings”. Plesk’s alternative, “DNS Template Settings” is available only to admin. Reseller’s DNS entries are merged with user DNS records.
4.2 Virtual directories don’t support URL redirection
In Helm 3 virtual directory can either map to a physical path or redirect to an URL. In Plesk URL redirection is not supported.
Such directories are not migrated.
4.3 All domains in a subscription share one IP
In Helm 3 there is an option (available only to admin) to assign different IPs to different domains in one package. In Plesk an IP is assigned to a subscription and all domains in a subscription use it.
Plesk uses single IP for all domains in subscription so the migration agent has to change domain IP sometimes.
The migration uses following algorithm to choose IP for subscription:
If domain is the only one in a package it's IP will be used; If there are several domains in a package, shared IP of some domain will be used; If all domains in package use dedicated IP and web service has shared IP, service's IP will be
used; If web service has dedicated IP, some shared IP from ones assigned to web server will be used; If all IPs on web server are dedicated, error will be reported and package will be skipped.
4.4 Forwarding domain limitations
In Helm 3 forwarding is a domain property, and can be turned on and off. It doesn’t prevent other domain properties from being changed. In Plesk hosting type can’t be changed to forwarding for
default domain. It can be changed for other domains, but making domain a forwarding domain removes all subdomains (and probably resets other settings too).
The web-settings of forwarding domains are not migrated.
4.5 Virtual directories can be created only in virtual directories
In Helm 3 virtual directories can be created anywhere in the directory tree. For example, it is possible to create virtual directory myvdir inside physical hierarchy a/b/c.
Plesk doesn’t allow that directly. However, there is a solution. First the migration creates physical
hierarchy a/b/c. Then at the root it creates virtual directory a targeting to /a, then inside a it creates b targeting to /a/b, then inside b it creates c targeting to /a/b/c. Then inside c it creates myvdir virtual directory.
4.6 Only one ASP.NET/ PHP version is configured in Hosting Plan
In Helm 3 reseller is able to configure both ASP.NET / PHP versions independently (there are limits for both versions).In Plesk’s “Hosting Plan” it is possible to specify either a single version that user will not be able to change or give user a permission to select between two versions (there are actually three versions, third being “None”). Hence the situation where user is able to select between single ASP.NET/PHP version and “None” can’t be migrated.
The migration gives the user full access (at least one limit is not zero) or disables the feature completely (both limits are zeroes).
4.7 Some hosting plan limits are migrated to toggles
Some hosting plan limits in Helm 3 are numbers, like “number of Perl installations”. In Plesk corresponding limits are toggles, like “enable/disable Perl”.
4.8 Some plan limits are not migrated
Not all Helm 3’s plan limits are migrated to Plesk. See Reseller Plan limits and Hosting Plan limits for the list.
4.9 Different file system structure
In Helm 3 users have full access to domain root (with one exception – they can’t access ‘logs’ folder). So it is likely that users store their data in domain root.
In Plesk users can’t write to the domain root. There are special folders like ‘wwwroot’ or ‘httpdocs’ which are available for writing, but all other folders are locked.
Since Plesk allows changing website root folder the solution is to replicate Helm 3 folders structure (except for logs folder) in httpdocs, and change site’s root to httpdocs\wwwroot.
Directory structure in Helm 3:
C:\domains\[domain] :domain’s root, [L,R,W]
|-wwwroot :site’s root, [L,R,W]
| |-sub :root for the ‘sub’ subdomain, [L,R,W]
|-logs :logs directory, [L,R,W]
|-db :?, [L,R,W]
4.10 Exotic ODBC DSN types
Helm 3 supports exotic ODBC DSNs: “Text” (.csv and .txt files). Plesk doesn’t support such DSNs.
4.11 Web Scheduler doesn’t support URLs
In Helm 3 web scheduler tasks can only access an URL. In Plesk scheduler can only execute scripts. Helm 3 also allows specifying secure folder credentials for the URL.
Web scheduler tasks are not migrated.
4.12 Undeletable domain in subscription
In Helm 3 customer can delete any domain from a package. In Plesk subscription has ‘special’ domain which can’t be deleted (that domain was created with subscription).

3.1.2 Servers
The migration is only for single server Helm 3 installations.
3.1.3 Services
All configured services are mapped to corresponding settings in Plesk. Because specific type of service is not specified during migration it doesn’t really matter that Plesk doesn’t support some of services that Helm 3 supports. Type of service is only that matters.
Here is the list of all Helm 3 services grouped by type:
Database Microsoft Access
3.1.3.1 Service settings
In Helm 3 some settings and limits are configured on per service basis. Settings are mapped to global Plesk settings, limits are transferred to every reseller plan.

3.1.3.1.1.1 Shared SSL
In Helm 3 name of shared SSL domain is configured in IIS5/6 service settings. In Plesk a special domain is created during the migration under admin with the same name as in Helm, so shared SSL URLs stays unchanged after the migration process. Content of shared SSL folders is migrated automatically.
Migration administrator should transfer SSL certificate manually to the Plesk domain.
Limitation: shared SSL status for “add-on domains” (2nd and subsequent domains in a package) is not migrated. All content of SSL folders is moved to private/SSL folder in Plesk, so a site administrator may enable shared SSL using Plesk UI and move the content using Plesk File Manager.
3.1.3.1.2 Mail services

3.1.3.1.6 Statistics services
Plesk doesn’t have settings for statistics services, so all settings are ignored.
3.1.4 Resources
In Helm 3 resources group service by type and specify load-balancing settings. It is not required to do resource migration for single server installations.
3.1.5 Resellers
Helm 3’s resellers are migrated to Plesk resellers.
Note resellers in Helm 3 are unable to create their own domains.
3.1.5.1 Reseller Plans
Helm 3’s reseller plans are migrated to Plesk’s reseller plans.
Helm 3 allows selecting configured resource for every type (Web, DB, Stats, Mail, and FTP). This selection is ignored for all resources but DB – MySQL / Microsoft SQL selection is honored and controls which limits are affected in Plesk’s plan.
3.1.5.1.1 Set Up Extra Features
Plesk doesn't have counterpart for extra features specified in reseller plans (hosting plan's extra features are migrated to Plesk's addons). However, extra features purchased by resellers are migrated by creating custom per-resellers plans.
For example, if reseller R was created under reseller plan PLAN and purchased extra feature "10 domains" in quantity of 7, migrator creates reseller plan "PLAN for R" with 70 more domains and signs up reseller R to that plan.

3.2.4 Users
Helm 3’s users are migrated to Plesk customers. In Helm 3 users are not signed up to a hosting plan, rather they create “package” for a hosting plan and then add domains to that package. In Plesk situation is close only users are called customers, and packages are called subscriptions.
3.2.5 Hosting Plans
Helm 3’s hosting plans are migrated to Plesk hosting plans.
3.2.5.1 Set Up Extra Features
Plesk's counterpart to extra feature defined at reseller level is addon. Addons are defined at reseller level (not on plan level as in Helm), so extra features from all hosting plans are gathered and migrated to reseller.
Plesk's addons have several limitations:
Addon names must be unique. o Solution: Unique name is created by adding internal addon identifier. For example, two
extra features named "Extra" will become "Extra" and "Extra #34" where 34 being the unique identifier.
Addon can be purchased only in single quantity. o Solution: For purchases in quantities other than 1 migrator creates fake addons and
purchases them once. For example, purchase of extra feature "Extra" in quantity of 11 will become purchase of extra feature "Extra x11".
Addon can be purchased only once. o Solution: For multiply purchases of same extra feature migrator creates fake addon and
purchases that addon once. For example, if feature "Extra" was purchased twice in quantities 10 and 1 migrator will create fake addon "Extra x11" and purchase that addon once.

3.3 User migration 3.3.1 Personal Details
User personal details migrated the same way as admin personal details.
3.3.2 Packages
In Helm 3 user creates packages for a reseller’s hosting plan and then adds domains to the packages. In Plesk packages are called “subscriptions”; customer can add many domains to a single subscription and can have several subscriptions.
However, there is a difference: in Plesk subscription has ‘main’ domain which is created with subscription and can’t be deleted. So there can’t be empty subscriptions.
3.3.3 Domain files
In Helm package is merely a group of domains, it exists only in Helm. Packages are migrated to Plesk’s subscriptions.
Note Shared SSL content of main domain are migrated into Plesk httpsdocs folder, SSL folders of addon domains are transfered into private/[domain name]/SSL folders.

Multi-recipient addresses are migrated to Email Address with disabled mail box (unchecked General/Mailbox) and enabled forwarding to several email addresses.
3.3.4.4 FTP Accounts
Corresponding location in Plesk: Websites & Domains/FTP Access.
Helm 3 creates one predefined FTP account for each domain. Account is named after domain (e.g. “domain.tst”), mapped to the home folder, has permissions to read and write. The account is not special and can be deleted. It will be migrated as an ordinary account.
Note that in Plesk users can’t write to the domain root. See Different file system structure limitation.

In Plesk Website & Domains\Web Statistics shows the current statistics, and Website & Domains\[domain]\Web statistics allows to enable/disable AWStats or Webalizer.
4 Limitations
Virtual directories don’t support URL redirection
All domains in a subscription share one IP
Forwarding domain limitations
Only one ASP.NET/ PHP version is configured in Hosting Plan
Some hosting plan limits are migrated to toggles
Some plan limits are not migrated
No alternative to “Multi-Recipient Addresses”
Different file system structure
Exotic ODBC DSN types
Undeletable domain in subscription
4.1 Resellers can’t add DNS templates
In Helm 3 both admin and resellers are able to add entries to “Global DNS Settings”. Plesk’s alternative, “DNS Template Settings” is available only to admin. Reseller’s DNS entries are merged with user DNS records.
4.2 Virtual directories don’t support URL redirection
In Helm 3 virtual directory can either map to a physical path or redirect to an URL. In Plesk URL redirection is not supported.
Such directories are not migrated.
4.3 All domains in a subscription share one IP
In Helm 3 there is an option (available only to admin) to assign different IPs to different domains in one package. In Plesk an IP is assigned to a subscription and all domains in a subscription use it.
Plesk uses single IP for all domains in subscription so the migration agent has to change domain IP sometimes.
The migration uses following algorithm to choose IP for subscription:
If domain is the only one in a package it's IP will be used; If there are several domains in a package, shared IP of some domain will be used; If all domains in package use dedicated IP and web service has shared IP, service's IP will be
used; If web service has dedicated IP, some shared IP from ones assigned to web server will be used; If all IPs on web server are dedicated, error will be reported and package will be skipped.
4.4 Forwarding domain limitations
In Helm 3 forwarding is a domain property, and can be turned on and off. It doesn’t prevent other domain properties from being changed. In Plesk hosting type can’t be changed to forwarding for
default domain. It can be changed for other domains, but making domain a forwarding domain removes all subdomains (and probably resets other settings too).
The web-settings of forwarding domains are not migrated.
4.5 Virtual directories can be created only in virtual directories
In Helm 3 virtual directories can be created anywhere in the directory tree. For example, it is possible to create virtual directory myvdir inside physical hierarchy a/b/c.
Plesk doesn’t allow that directly. However, there is a solution. First the migration creates physical
hierarchy a/b/c. Then at the root it creates virtual directory a targeting to /a, then inside a it creates b targeting to /a/b, then inside b it creates c targeting to /a/b/c. Then inside c it creates myvdir virtual directory.
4.6 Only one ASP.NET/ PHP version is configured in Hosting Plan
In Helm 3 reseller is able to configure both ASP.NET / PHP versions independently (there are limits for both versions).In Plesk’s “Hosting Plan” it is possible to specify either a single version that user will not be able to change or give user a permission to select between two versions (there are actually three versions, third being “None”). Hence the situation where user is able to select between single ASP.NET/PHP version and “None” can’t be migrated.
The migration gives the user full access (at least one limit is not zero) or disables the feature completely (both limits are zeroes).
4.7 Some hosting plan limits are migrated to toggles
Some hosting plan limits in Helm 3 are numbers, like “number of Perl installations”. In Plesk corresponding limits are toggles, like “enable/disable Perl”.
4.8 Some plan limits are not migrated
Not all Helm 3’s plan limits are migrated to Plesk. See Reseller Plan limits and Hosting Plan limits for the list.
4.9 Different file system structure
In Helm 3 users have full access to domain root (with one exception – they can’t access ‘logs’ folder). So it is likely that users store their data in domain root.
In Plesk users can’t write to the domain root. There are special folders like ‘wwwroot’ or ‘httpdocs’ which are available for writing, but all other folders are locked.
Since Plesk allows changing website root folder the solution is to replicate Helm 3 folders structure (except for logs folder) in httpdocs, and change site’s root to httpdocs\wwwroot.
Directory structure in Helm 3:
C:\domains\[domain] :domain’s root, [L,R,W]
|-wwwroot :site’s root, [L,R,W]
| |-sub :root for the ‘sub’ subdomain, [L,R,W]
|-logs :logs directory, [L,R,W]
|-db :?, [L,R,W]
4.10 Exotic ODBC DSN types
Helm 3 supports exotic ODBC DSNs: “Text” (.csv and .txt files). Plesk doesn’t support such DSNs.
4.11 Web Scheduler doesn’t support URLs
In Helm 3 web scheduler tasks can only access an URL. In Plesk scheduler can only execute scripts. Helm 3 also allows specifying secure folder credentials for the URL.
Web scheduler tasks are not migrated.
4.12 Undeletable domain in subscription
In Helm 3 customer can delete any domain from a package. In Plesk subscription has ‘special’ domain which can’t be deleted (that domain was created with subscription).
