Hi,
The customer has 4 Exchange 2010 mailbox servers, each has a public folder database. We are at the end of the migration and need to migrate public folders over. I have done this a few times (2010 to 2013/16/O365) and it's easy enough. However, what the MS documentation doesn't tell you is how to deal with when you have 4 servers that have different counts of public folders.
Looking at this: https://learn.microsoft.com/en-us/Exchange/collaboration/public-folders/batch-migration-from-previous-versions?redirectedfrom=MSDN&view=exchserver-2016
When I run: .\Export-PublicFolderStatistics.ps1 <Folder to size map path> <FQDN of source server>
I get a different answer from the machines. This means the public folders are not in sync / the same, across all 4 public folder databases.
What would be the best way to fix this to allow us to migrate everything without missing things?
Like I said, if this was a single server - or all 4 servers were in sync, then this would be easy. But as I am not overly familiar with 2010 public folders in general, I have no idea why they are out of sync and therefore what the best way to catch all data at the migration would be.
Any help would be great.
Cheers
James
