Used this in my live environment this week, VMW 5.5u2, Windows server with separate SQL 2008r2 DB Server.
Worked like a charm apart from one small issue.
We used a named instance for our original VCDB and it doesn’t appear to like that at all.
Solution was simply to put a copy of the DB into the root instance then it worked perfectly!
I hope this saves anyone else some aggravation.
