Can't uninstall Exchange 2007 after upgrading to Exchange 2010.

Trying to decommision the old virtual exchange 2007 SP2(windows server 2008) server. We have upgraded to Exchange 2010(Windows server 2008 R2) which sits on its own virtual box.

I assume that the problem is with the schema version. Not sure how to go about it.

Any suggestions are greatly appreciated.

Hi, Sunny
I have tried the first two methods. They didn't work. This is that old Exchange that caused me a lot of sleepless nights when its hub transport service stopped working and transition to Exchange 2010 went really bad with missing public folders.

I deleted Mailbox store from it without any issues. Public folders had to be manually deleted via ADSIedit. It kept complaining about replicas still existing.

Now, I just want to gracefullly shut it down and get rid of it.
