REALLY old system upgrade help needed 14.04/v0.27 to 22.04/current

There’s a user here that got various advice, but they never reported what worked for them.
My thinking is that the easiest way is:

  1. Read Mail-in-a-Box Maintenance Guide
  2. Update to v0.30
  3. Save your user-data folder
  4. Install the new machine with Ubuntu 22.04 and the latest Mail in a Box
  5. Restore the user-data folder, as per the maintenance guide.
  6. See if it works.

But that might not work, as JoshData indicates you will skip a number of upgrade steps. If it doesn’t work, you might have to upgrade with an intermediate step via Ubuntu 18.04. So:

  1. Read Mail-in-a-Box Maintenance Guide
  2. Update to v0.30
  3. Save your user-data folder
  4. Install the new machine with Ubuntu 18.04 and the latest Mail in a Box
  5. Restore the user-data folder, as per the maintenance guide.
  6. Save your user-data folder
  7. Install the new machine with Ubuntu 22.04 and the latest Mail in a Box
  8. Restore the user-data folder, as per the maintenance guide.
  9. See if it works.

You might want to do a dry run of this first, before you stop using the old server.

Make sense?
