The documentation said that it wouldn't work with the migration-tool and a local to local master. We are two a small shop with just one 7205. Reading this thread I grabbed the gauntlet and went for it. I'm using the migration tool from 8.5.0.0 and after a few problems with it not booting in the Nutanix-environment (got it up by going through rescue-mode and starting multi-user from there) I then started the upgrade from 6.5.4.13 to 8.5.0.0.
Everything seems OK, but the migration tool is still sitting with "SETTING LICENSES FEATURE BITS 95%" and a spinning wheel. It has been sitting there for half an hour now. I can see the licenses in the management console though.
Should I just wait?
The log-window has as a last message "cleaning passwords" something something and then Task MigrationTool.start_migration... MIGRATION COMPLETED... result SUCCESS.
That looks good to me, but it's still spinning at 95%
One good thing with the current situation is that I can have the controller down at daytime. Nobody's at the office using the wifi.
Stay strong
