Finally attempted upgrade from 9.10.2-U6 to 11.1-U6, key word attempted

First I'll start with saying I sure am glad it's so easy to move back! :)

Was feeling pretty good at first since things appeared to go smoothly, but could not get my Plex server going. Other jails worked fine. I could not ping 8.8.8.8 until unchecked VIMAGE for the Plex jail. Then I could not get Plex to start in the jail. Looked around the forums but could not find anything that worked.

You may need to backup your Plex data and completely remove that jail. Then you can make a fresh one under the new version of FreeNAS. I had to do that a couple times over the years.
You are going to need to rebuild all your jails under the new iocage jail infrastructure anyway because the old warden jails are not supported any more.

Hey Chris that is what I was figuring. Exactly what Plex data do I need to backup so I don't lose what movies and TV shows I've already watch?
