Hi Ken. I am indeed working on a copy. We're building an entirely new server for this migration. The old server will be pulled offline and used for archival purposes.
I have taken your advice and replaced the 32-bit services with 64-bit versions. The error persisted so I followed your second piece of advice. Sure enough, there was a 9GB backup file in one of the folders. I have removed all the 1.9 backup files and restarted the upgrade. The upgrade is now proceeding nicely.
Thanks for the assist. I will post another note when it finishes (or if it fails).
