Uninstalling Exchange 2007 - Moving Replicas

[TomHD]

Hello All,

 

I have been tasked with decommissioning our old Exchange 2007 server and would like to help to understand exactly what I'm doing. I have run the readiness checks and failed on the Mailbox Role Prerequisites:

 

 

We have an existing Exchange 2010 running so I'm guessing I need to move the replicas to the 2010 server rather than remove them?

 

Thanks, TomHD

Public folders have always been 1 thing I never looked forward to when decommissioning exchange servers. Luckily we never used them as such but always had the database there.

 

From what I recall in the last migrations, you need to check that all replicates have been moved over to the exchange server.

Unfortunately, I don't have the powershell commands still to hand but it usually ended up being the system folders left over that wouldn't let me uninstall the role.

 

There were some powershell commands which forcefully removes the system folders NON_IPM _SUBTREET, Free/Busy Info etc....

 

Once I'd done that it let me remove the role without any issues.

 

I was always able to find the solution by googling migrating public folders or removing last public folder database to find the solution to this issue.
