*My* recommendation would be to:

* Find a time you can dedicate to the cutover, where no
  "critical" recordings are to be made (it can be done in
  less than 10 minutes, if you have done everything before,
  and it could take multiple hours if you get unlucky)
* Stop the BE
* Make a backup of the DB.
* Make another backup of the DB
* Make sure you know where the backups are.
* Make sure the size of the backups seems "reasonable"
  (zero length files should be a hint it did not work well).
* Run mythtv-setup, and "delete all capture cards"
  (and not "delete all capture cards on <this host>")
* Run mythtv-setup, and "delete all video sources"
* Follow the directions in the Wiki regarding the
  Prime.  Add the device, add in a (schedules direct)
  video source, make the input connections, and
  be sure to "fetch listings data" (there is no scan
  for an OCUR tuner).
* Run mythfilldatabase --dd-grab-all
* Start the BE
* Test a (simple) recording.
* Enjoy a cold tall one.

Recovery, if needed, would be to restore the
DB and restart the BE.
