I'm trying to pick up the pieces of a poorly deployed 2003-to-2007 migration. This has been a not so subtle reminder that Ignorance is dangerous in this business.
Our two Exchange servers, 2003 and 2007 have been co-habitating for quite some time now. Mailboxes have all been successfully moved, and public folder replication *seemed* to be working too, although I never actually drilled down to the various folders on the new server to confirm item counts (first mistake). All seemed to be working as expected, until we started trying to eliminate the old 2003 server.
As the old server was no longer doing anything but replicating public folder data, I performed a "move replicas" to the new server (probably the second mistake), thinking this would force the new server to host the PF database. Exchange obediently complied error free. The contents of the old servers public folder emptied. However, looking in Outlook these public folders are incomplete, and do not contain much of the data that existed in the old PF. As I said, I cannot verify that the new PF had properly replicated old PF data in the first place. Obviously what I had been seeing before was on the old server.
In short, I've lost a lot of old PF data and there doesn't seem to be a way to get it back. I had turned off replication to the old server initially, thinking things were good after the move, but I have subsequently turned it back on and see "In Sync" status on the old server and "Both Modified" on the new. Functionally, the old and the new Exchange servers are speaking to each other and replicating PF's again. Still, PF data is missing, it appears, there's no longer anything left of the original server to replicate.
I have a backup of the old PF's database, not PST's (third mistake) which I could (theoretically) restore back onto the old server as a last resort I suppose. But I find it difficult to believe those PF's are simply "gone", discarded by the "move replicas" operation. The old PF data should not have deleted if the new server didn't have the data in my mind. The folder structure is all there, specific data in many of the folders too, but many of the folders simply show zero items.
I'm just looking for a little direction on where to start, what I might have done wrong, but more importantly, what has happened to that data. I can only assume it was never replicated in the first place, but if so, why didn't they stay on the old server if they couldn't move?
Any assist would be appreciated. I'd grade my Exchange expertise at about 3 out of 10.
