Issues with Public folder migration

Question

Hi,
I'm at the end of an Exchange 2007 to 2010 migration. 99.9% of mailboxes have been moved to the 2010 Mailbox server. The environment is : 2007 SP3(1 X CAS, HT and MBX), 2010 SP3 (1 X CAS, HT, and MBX). I'd really appreciate some help on some Public folder
replication issues:
I have replicated the default public folders across using: 
AddReplicaToPFRecursive.ps1 -Server 2007MBX -TopPublicFolder "\" 
-ServerToAdd 2010MBX
1) When I get public folder statistics from each Exchange mailbox, there are a few public folders where there are 1 or 2 items on the old server that are not on the new one.  There is one public folder on the new server that is not on the old one. I've
updated the hierarchy but that hasn't helped. Is it possible this is because of the folder being created on the new server later on? Is there any way to easily find the folder location in a complex hierarchy?
2) When I try to get public folder statisctics on the 2007 MBX server, I get the following:
[PS] C:\Documents and Settings\ha>Get-PublicFolderStatistics >d:\test\test2
.txt
WARNING: Object

0000652320000 has been corrupted and it is in an inconsistent state. The
following validation errors have occurred:

How do I find the object referenced by the series of numbers (for example, 000000001A447390AA....)?
I'm also  seeing some backfill events (even ID 1020) on the 2010 Hub transport.
3) Which System Public Folders should be replicated from 2007 to 2010 prior to moving them using the moveallreplicas script? At the moment, the following are replicated between both servers: 
StoreEvents (Old server), Schema-root, Schedule + Free Busy (and sub folders), OWA Scratchpad (Old Server), Event's Root, Offline address Book (/o=Exchange2003/cn=addrlists/cn=oabs/cn=Default Offline Address List & EX:/o=Exchange2003/ou=Exchange
Administrative Group (FYDIBOHF23SPDLT) )
Other system public folders are not replicated.
Thanks,
HA

Hi,
1) You can use the Get-Publicfolder -Recurse | Format-List Name, *path cmdlet to check the parent path of public folder.
2) You can use the Get-PublicFolderStatistics  | fl name, *identity command to get the identity of public folder. View the list of identity you get, and check if you can find the following object.
000000001A447390AA6611CD9BC800AA002FC45A030002640DAF3EE76D4783F6C0C0CD5AD03F015
6AA8A1ECE0000
3) When you migrate public folder from Exchange 2007 to Exchange 2010, you need to replicate the following system public folders, you can remove the others.
SCHEDULE+ FREE BUSY, OFFLINE ADDRESS BOOK and EFORMS REGISTRY(if you use Organizational Forms)
