We are upgrading a exchange 2003 environment to 2010.
I spun up a new VM for the exchange 2010 and got it installed succesfully. However I need to uninstall the version of exchange I put on there with a different version.
Currently in this setup, there is absolutely nothing on the exchange 2010 box, everything is still on the exchange 2003 server. I tried uninstalling exchange 2010 via add / remove programs and it gave me an error about arbitration mailboxes. I was able to delete those via adsiedit, but it is still giving me the same error.
So I got to thinking..since this is a VM, it might be quicker for me to just blow away the VM and create a new VM, however I'm not so sure.
My question is this:
On the Exchange 2003 server in the exchange system manager I see the new exchange server I installed. Is it safe for me to blow away the new exchange server or do I need to delete the new exchange server from the exchange system manager? If I do that will that break anything with the current exchange 2003 server?
Hopefully that makes sense.
