I'm running in a coexistence 2007 and 2013 environment. However when I started this project I knew nothing about exchange migration. so I installed a vm in the environment to test with and was only suppose to use it for getting to know exchange 2013. Then my 2007 server which had about 900 mailboxes started re-booting constantly. after working with dell's tech and replaced parts to which it did nothing. So management bought new hardware and I began migration. Everything seems to be working but I want to uninstall the 2013 vm cleanly while I'm decommissioning the 2007 servers from the environment. does anyone have a link to a step by step so I don't have any bad experiences? Any help would be greatly appreciated. I did this migration after ONE class so I'm a little nervous about messing up what I have achieved.
Both servers are running on server 2012 if that matters.
