Convert UFS to ZFS

[kevinfason]

Well not really, thats the gist of what I want to accomplish though. I understand a reinstall is required to use ZFS. I did find this as a compromise and will likely go this method. ZFS is one of two features I miss from PFSense.

Before doing that though I wanted to inquire if there is a resource to restore additional data not included in a backup such as vnstat database, logs, etc. Or maybe a list of what is not included in the backup? I can grab the vnstat database and zenarmor backup. I could without various logs but would be nice to transfer all the living data the system has accumulated.  In my case I am NOT using the community repository yet, just the built-in one with a few plugins enabled.

  os-theme-cicada
  os-vnstat

ZenArmor is installed but not configured past the initial state. I read you trigger a cert update for letsencrypt. So I have zenarmour, vnstat, and letsencrypt figured out at this point. The other feature I miss being online backups but I am doing that via other methods so happy on that front.
