TrueNAS-12.0-U8.1 Updates to 13?

[gjh1967]

I am confident that manually formatting the drive and installing the new OS will do the trick.
Don't forget to save your config if you don't want to setup everything again!

Solved my own issue.
It turns out that somehow one of the upgrades got installed to a spare SAS drive. i pulled the drive out that was indicated as boot-pool. Truenas didn't like that , but that was expected. Rebooted into the ISO for 13.0-U5. did a fresh install. rebooted. Uploaded my saved config and rebooted again. All pools and jails working and now showing the new 13.0-U5 version with trains showing scale as an upgrade option.
Its only taken me 15 months to get this far. :-0

Thanks for your help.
