We are currently running SourceOne 6.8 with Exchange 2007. Once SourceOne 7.1 is released (hopefully still targeted for November??) we are going to be upgrading SourceOne followed by an upgrade/migration to Exchange 2013. Since we shortcut attachments, is there anything we need to do before moving mailboxes from 2007 to 2013? This is not in regards to the setup needed on the server side - this question is specific for making sure we don't do something to break the shortcut link when moving a mailbox from one server to the other.
