Hello everyone,
I had some problems with my old Exchange 2010 as it was freezing from time to time. I decided to install a new Exchang 2010 server. I transferred mailboxes, MX record stays the same and I routed all e-mails to the new server now. I disconnected other server from the network to test is everything working fine and so far so good.
My bigger concerns are following now:
a) how to transfer license as I wanna use the same license key which old server uses.
b) How to Uninstall old Exchange 2010 server.
In regards to license transfer I don't want to get to the point where I am going to get message that I used the same license key on another server. Do I have to deactivate license on the old server? How do I do that. Maybe uninstallation of it will send a signal to Microsoft that license is gone. Has anyone come across this kind of issue? So what do you think should I uninstall old server first before I enter this license?
In regards to my second question which is related to the first one. How do I properly remove old Exchange 2010 server. I found some instructions that I should just go to "programs and features" and uninstall it this way or run a setup from CD. Other instructions says that I should uninstall database over power shell and uninstall public folders etc. I would like to do it as clean as possible as I don't want my new exchange or any of DCs to look for missing Exchange later. Which option properly uninstalls Exchange 2010 from my domain and from AD. I wanted to add that my Exchange2010 are on Windows Server 2008 R2.
I just wanted to add that I phoned Microsoft to ask about it but they said that I have to pay for support otherwise they can't help me. What would you do first? license or uinstallation of old Exchange 2010? I still have over 100 days of trial on new build server.
