Exchange 2007 to 2013: Public Folders Migration issue
I got this unique issue with no exact issue or solution available over the internet so I am sharing this.
Exchange 2013 CU8 lab environment for POC configured as per Microsoft Preferred architecture mentioned here.
4 Exchange 2013 CAS+MBX – 2 servers per AD site
1 FSW in 3rd AD site.
Domain Controller in every AD site.
Single Exchange 2007 SP3 Ru 16 with one mailbox and one PF database.
When I ran the below command
“New-PublicFolderMigrationRequest -SourceDatabase (Get-PublicFolderDatabase -Server <Source server name>) -CSVData (Get-Content <Folder to mailbox map pathfilename.csv> -Encoding Byte)”
I got the error.
Resource ‘Processor’ is unhealthy and shouldn’t be accessed.
Initially I fixed the issue by reducing the number of mailboxes to 1 but this just locked down my migration for rest of the mailboxes.
Then I did a roll back
I just realize that 2 PF mailboxes were located in the database in the different AD site.
Move the database to the primary AD site where I had legacy Exchange 2007 database.
Rerun the PF migration and it worked perfect.
Keep all PF mailboxes in the same AD site until you migrate Public folders from legacy. Post migration you can move these mailboxes to different AD site.
Keep all migration restricted to one AD site at a time.
