Public Folder Migration from Exchange 2003 or 2007 to Exchange 2010

Step 1: Replicating 2003 or 2007  PF’s to 2010

Add PF replica’s to an Server:

.\AddReplicaToPFRecursive.ps1 -server "/2007 Server" -TopPublicFolder "\" -ServerToAdd "Exchange 2010 Server"

Replicate the System Folders to an Exchange 2010 Server:

.\AddReplicaToPFRecursive.ps1 -TopPublicFolder "\NON_IPM_Subtree" -ServerToAdd "exchange2010 server”

If you are planning to have multiple Exchange 2010 PF servers, you can repeat the Cmdlet

From the Exchange 2010 server: Update-PublicFolderHierarchy -Server "Exchange 2010 Server"

Step 2: Moving Exchange 2003/2007 PF’s to Exchange 2010

As a last step, after you confirmed that all the PF have been replicated to the Exchange 2010, you can move all replicas from Exchange 2003/2007 to Exchange 2010. The "move all replicas" will actually remove the Exchange 2003/2007 replicas.

To move all Exchange 2003/2007 replicas to Exchange 2010, which will actually remove the Exchange 2003/2007 replicas:

.\MoveAllReplicas.ps1 -Server "Exchange 2003 Server" -NewServer "Exchange 2010 Server"

Additional Cmdlets

To a list of the replicas in the public folder hierarchy: Get-PublicFolder -recurse |fl name,replicas

For System Folders: Get-PublicFolder -recurse \non_ipm_subtree |fl name, replicas

To compare content replicated between the source and destination servers: Get-PublicFolderStatistics
