SMART  Considerations  for  Active  Directory  Migrations  

•  AD  is  the  nexus  for  your  application  infrastructure  

•  Few  directories  are  as  visible  and  impact  end  users  as  much  as  AD  

•  Users’  AD  identities  are  used  to  access  resources  

•  AD  identities  are  an  inescapable  part  of  corporate  life  

The  Role  of  Active  Directory    in  Your  Environment  

•  Mergers,  acquisitions  and  divestitures  

•  The  desire  to  reduce  complexity  which  in  turn  generates  lower  maintenance  costs  

•  Some  network  topologies  inhibit  the  adoption  of  new  technologies    (i.e.  Office  365)

•  Windows  Trust  Requirements  

•  Windows  Password  Migration  Requirements  

•  NetBIOS  Naming  Resolution  Requirements  

•  DNS  Naming  Resolution  Requirements  

•  Group  Policy  Requirements  

Active  Directory  Domain  Migration  Checklist  

•  Migrations  are  usually  gradual  events  

•  Even  small  environments  should  plan  for  coexistence  

•  Neither  the  source  nor  target  environment  are  likely  to  remain  static  during  the  migration  

•  Synchronization  maintains  transparent  interoperability  and  minimizes  risk,  downtime  and  interruptions  to  users  regardless  of  migration  state  

AD  Synchronization  versus  AD  Migration  

•  User  Provisioning  

•  Group  Management  

•  ACL  Administration  

•  Password  Synchronization  

•  Continued  Reporting  

On-­‐Going  Operations  During  An  AD  Migration  Managing  AD  Environment  During  Coexistence  

The  End  User  Experience  During  an  AD  Migration  

•  This  is  where  the  rubber  truly  meets  the  road  

•  Migration  must  maintain:  

•  The  user  profile  

•  The  drive  mappings  

•  The  Outlook  connectivity  

•  User  workstations  need  to  stay  connected  (during  the  actual  migration)  

Maintaining  User  Functionality  and  Productivity  

•  Exchange  is  reliant  on  Active  Directory  

•  The  migration  of  a  mailbox  directly  impacts  the  AD  user  experience  and  vice  versa  

•  Any  migration  project  must  account  for  the  relationship  between  AD  and  Exchange  

The  Relationship  of  AD  Migrations    with  Messaging  Migrations  

•  Exchange  is  wholly  dependent  upon  AD  for  directory  services  

•  Mailbox  objects  intersect  AD  identities  

•  A  split  Global  Address  List  can  make  collaboration  challenging  

•  A  user’s  Outlook  profile  is  tied  to  their  workstation  profile  

The  Effect  of  AD  Migrations    on  Messaging  

•  Replace  remote  office  domain  controllers    

•  Convert  server  local  users  and  groups  to  domain  accounts  to  simplify  server  management  

•  Consolidate  legacy  server  to  physical  or  virtual  Windows  severs  for  better  performance  and  management    

•  Replace  aging,  failing,  or  unsupported  legacy  file  servers  

The  Importance  of  Windows  Server  Migration  The  most  overlooked  aspect  of  Active  Directory  migration  

•  SIDs  are  not  portable  across  member  severs  

•  Access  to  files,  folders  and  shares  must  be  maintained  during  and  after  the  migration  process  

•  Changes  must  be  synchronized  during  the  migration  process  

•  User's  mapped  drives  must  be  maintained  after  the  migration
