Upgrading RT in Windows to 3.4.X

I’ve got a stable RT (3.0.12) instance running on Windows Server 2K3. I’d
like to upgrade it to 3.4, but am wary of the Test version. How would I
perform the upgrade? Has anyone tried running doing this under Cygwin? I’m
currently replicating a backup of my database to a development box to test
