nothing in any of my jails right now is even that important. my weather station is down, so I don't need the mysql jail that hosted its data (its all backed up), and my other jails are all just minor things, one that a friend was using to sftp/scp into my nas, but he's not doing that anymore, another I built to host a postgresql server but its not being used, etc etc.
I just want to know the upgrade process, or if its even doable.
