Fail to see what that has to do with the problem at hand?

That's what he did, didn't he?
And to OP and Sybrand: this seems like a normal, manual upgrade to me, somewhat oddly started with a database that wasn't there originally.
But the procedure is standard: first you upgrade the
software tree, then the instances. You instance did
not need an open resetlogs, as it was a cold backup.
It just needed startup in upgrade mode, and the
update scripts allied.
Of course, real DBA's do not use GUIs!
