We are almost done with migrating a segregated Exchange2007 Server to Exchange 2013 with address book policies. We decided to migrate using a legacy Namespace and have not had any issues so far. All mailboxes were moved to the new Server and all seems to be fine.
As the offline address book Generation process has changed i wonder how to migrate the offline address books over to the new Server. doing the move-offlineaddressbook request Fails with the following error: "Failed to create the ExchangeOAB Folder on the target Server...."
is there any common procedure for this. i have not found anything in TechNet so far.
