Moving and removing public folder database replication with Exchange 2010

If you have recently upgraded from an earlier version of Exchange too Exchange 2010 and you have now decided to decomission the oldere version of Exchange you might be required to move all of your existing public folders to the newer server.

We should firstly add our Exchange 2010 server as a replica to ensure the migration goes smoothly by making use of the following script:

.\AddReplicaToPFRecursive.ps1 -TopPublicFolder "\" -ServerToAdd "Exchange 2010 Server"

and also ensuring the 'SYSTEM' public folders are added as well:

.\AddReplicaToPFRecursive.ps1 -TopPublicFolder "\NON_IPM_SUBTREE" -ServerToAdd "Exchange 2010 Server"

We should ensure that after adding the replica server that all of the heiracry and content has been replicated and is upto date with:

Update-PublicFolderHierarchy –Server “<Exchange 2010 Server>”

 Then confirm that the appropraite the public folders are listed as being replicated with the new Exchange 2010 server:

Get-PublicFolder -recurse \ | fl name, replicas

and

Get-PublicFolder -recurse \non_ipm_subtree | fl name, replicas

We can then run the following script with Exchange 2010 to move all public folders to the 2010 instance:

.\MoveAllReplicas.ps1 -Server Exchange2003 -NewServer Exchange2010

 * Note: Do not include the source server if Exchange 2003 as the script will throw a tantrum complaining: "Server 'Exchange 2003' is running Microsoft Exchange 2003 or earlier." ) *
