Exchange 2003 migration to 2010 - public folder instances not emptying

Exchange 2003 SP2 Enterprise - 1 front-end, 2 back-end
Exchange 2010 SP3 UR2 (CAS are STD, Mailbox servers are Enterprise)

Our goal is to decommission the Exchange 2003 servers.  All mailboxes have been moved to 2010.  I believe that all public folder data has been moved with the exception of the System Public folders... I'm not sure if they have been moved yet.  Whats the easiest way to check this?  There is one Public Folder store on each 3 2003 servers.  There are 2 Public Folder stores on 2010 side.  

Problem:  I cannot get the public folder instances to empty on 2 of the 2003 servers after trying Move All Replica's through ESM (on 2003 side) or MoveAllReplicas.ps1 (2010 side).  

However, I did successfully get the public folder instances to empty on one of the 2003 servers and was able to safely delete the Public Folder store (i had to mount all old mailbox stores on that server).

One weird thing is that in ESM, when i go to Administrative Groups - <2003 Group> - Folders there is nothing there.  I believe this was deleted.  Should the public folders be listed here?  Is this my problem with why the PF instances are not being emptied?

Other possibilities I was thinking...

- Do all the mailbox stores in the server need to have a different default public folder in order to get the public folder replicas to empty?


Does anyone have any suggestions?  Let me know if you need more info.
-Thanks!

Okay, some questions back at you.

1/. When you do move all replicas from the Exchange 2003 servers what happens? Do you get errors messages? Does it complete? Any Public Folder entries in the Event Logs?

2/. If you go to Public Folder Instances are these empty on the problem servers?

3/. Does the Mailbox Database still exist on the 2003 server? You can't remove the Mailbox Database until all Public Folder Replicas have been moved. The System Attendant still needs a mailbox on 2003 server as well to make this move.

4/. Make sure the System Attendant service is still running on the 2003 servers.

The Public Folder hierarchy was likely moved to the new 2010 Administrative Group. You may see these in the 2010 Administration Group on the 2003 ESM. So they were probably moved and not deleted.

We have since resolved the issue but I will still answer your questions...

diggisaur...
1. We had to turn ALL logging on to see event log items.  No, it did not complete.
2. The PF instances are not empty, this was our problem.
3. Yes, the mailbox databases still exist on the problem servers
4.  System Attendant service was running

We resolved this issue by creating new connectors from the problem servers to the servers we wanted to replicate to.  We replicated again and all the PF instances went away.
Thanks for all the help!
