Public folders - exchange 2007 to 2010 - decomissioning 2007 replica

Hi All,

This is probably a quick one.

We have completed a migration to Exchange 2010 and we're now decomissioning Exchange 2007. All of our users point to the public folder database on the 2010 environment and it has replicated completed.

What are the steps I now need to perform to decomission exchange 2007 entirely? Is it just a case of removing the exchange 2007 server's replica? I.e. \RemoveReplicaFromPFRecursive.ps1 -TopPublicFolder "\" -ServerToRemove "The Exchange 2007 Server?"

And setting the "Exchange 2010 OAB" as default and removing the "Default Offline Address Book" still sitting on Exchange 2007?

To clarify, we have no users on Exchange 2007 anymore.

You are almost set. Before you remove the Default GAL, you must set the Offline Address Book on all databases to "Exchange 2010 OAB". Organization Configration->Mailbox->Database Management. Open Database Properties->Client Settings->Offline Address Book or you may use the following command to set it for all databases

Get-MailboxDatabase | Set-MailboxDatabase -OfflineAddressBook "Exchange 2010 OAB"

And yes, you can use the RemoveReplica script to remove the public folder replicas from Exchange 2007.
