Hi Neil!

This is about *rolling* upgrade. If I understood Howard correctly, he's not trying to do a rolling upgrade. He's simply trying to upgrade standby first, in order to have standby ready when the primary is upgraded. And that would, almost certainly, work.  However, there is nothing better than trying. Put VirtualBox on one of your servers and try doing what  you need. If the thing succeeds with a small DB containing only demo accounts, it will most likely succeed with a large production DB.
