[mythtv-users] Migrating recordings from <= 0.27 to 31

I'm getting ready to replace a family member's MythTV backend with a new 
PC. The new PC will have MythTV 31. The old PC has a > 7 year old MythTV 
(0.27 or earlier) with a few dozen recordings. The recording schedule is 
pretty simple so I'm OK with starting from scratch with a new 
configuration were it not for the recordings.

Originally I'd thought I'd convert the recordings to videos on the old 
backend then 'scp' them over to the new backend, but I'm not having any 
luck with the mythvidexport2.py script I downloaded: a job gets added to 
the queue but sits there and never runs. Also I see that the script has 
to do some kind of encoding of the video file. This has me concerned 
that it might get time-consuming to migrate a lot of recordings this way.

Now I see that it might be possible to restore the old backend's 
database on the new backend system.


1. What is the correct way to submit a user job and force it to run as 
soon as possible?

2. Is it safe to use the mythconverg_restore.pl script to do a full 
restore of a backup taken on a <= 0.27 backend to a 31 backend?

3. Assuming I can do a full database restore, is there anything I have 
to do with the recordings other than 'scp' them to a recordings storage 
directory on the new backend?
