I have a SharePoint server at easyname.domain.com
I want to upgrade that server's OS and hardware by building a new system with better components.
The problem is, when you install SharePoint, a great deal of the system is tied to it's identity. So if I installed a mirror Farm at easynametemp.domain.com, and then did a backup restore from the original farm, I cannot just rename the machine and have everything work.
I assume there's a standard way to do this so that your farm isn't offline for an hour or two while you construct the machine.
