If the structure of the sim VM didn't change across releases you can generally pull off an upgrade if you can obtain the upgrade .tgz. They aren't published, but if you've ever replaced a failed CF boot device, obtaining one is pretty much that procedure in reverse.
I updated my vsim from 8.2.2RC2 to 8.2.1GA using option boot 7. The upgrade worked and system image show is now ga. However the licenses and commands don't work. A license-v1 error when I run license show.
Any changes or way to get ga in the vsim? Upgrading 8.2 to 8.2.1rc1 and rc2 all worked the same way. But 8.2.1 doesn't want to run as a licensed system after upgrade.
I have a vm snapshot so reverted back to 8.2.1rc2 and all good. It was 8.1 originally and went to 8.2.1rc1 then rc2. All good. Then 8.1.2ga caused this. Will try again and see. Might be an issue if it started 8.1.
Fixed it. Vol0 filled up. The 8.1 vsim original setup had aggr and vol snapshots enabled. Rolled back vmsnap, deleted vol and aggr snaps and schedule and upgrade ran fine 8.2.1rc2 to 8.2.2ga via option 7
