The above guide on how to migrate SBS2003 to 2012 Essentials is missing an essential step. In it's first section, entitled "To Uninstall Exchange Server 2003 from the Source Server" there is a note stating that all data must be removed from the exchange server first and that the info on how to do that is earlier in the guide. It isn't however on the page that is linked nor have I found it anywhere else in the guide!
I want to make sure I do this safely and properly - is there anyone out there in this forum with the step that is missing from this guide?
