Hi.
I am preparing for an account & mailbox migration from Domain A\Exchange 2007 to Domain B\Exchange 2010. I am going to following the steps below to migrate the users, can you please advise if there are any pit falls in my plan. Please note I am not worried about mailing between Org’s or Free/Busy as I plan to migrate all the mailboxes over a weekend.
Domain A:
· Domain Function level: Windows Server 2008
· Forest Function Level: Windows 2003
· Exchange 2007 SP2
· Email address: user@domainA.com
Domain B:
· Domain Function level: Windows Server 2003
· Forest Function Level: Windows 2003
· Exchange 2010 SP1
· Email address: user @domainB.com
These are the steps I am going to use
1. Migrate accounts using ADMT 3.0
2. Extract Prepare-MoveRequest.Ps1 on Exchange 2010
3. Enable-MailUser -Identity JBloggs -ExternalEmailAddress jbloggs@domainA.com
4. Run this cmd on Exchange 2010: Syntax: $Local = Get-Credential
5. Followed by Syntax: $Remote = Get-Credential
6. .\Prepare-MoveRequest.Ps1 -Identity "DN of a user from SourceForest" -RemoteForestDomainController "FQDN of Source DC" -RemoteForestCredential $Remote -LocalForestDomainController "FQDN of Target Forest DC" -LocalForestCredential $Local -TargetMailUserOU "Distinguished name of OU in TargetForest" –UseLocalObject
7. New-MoveRequest -Identity “Distinguished name of User in Target Forest” -RemoteLegacy -TargetDatabase “E2K10 Mailbox Database Name” -RemoteGlobalCatalog “FQDN of Source DC” -RemoteCredential $Remote -TargetDeliveryDomain“Target domain name”
