You are correct there are some really old versions of MythTV that you
can't directly update to current versions but you should be fine with
anything like 0.25 or newer.
One thing I would say is depending on how big your database is and how
many recordings, videos etc. you have it could take a long time to
update the DB so be patient don't assume because it looks like nothing
is happening that the update has frozen it could just be taking a long
time especially with a large DB and an older version of MythTV with a
lot of updates to perform. Also the backup that is created before the
update can take a long time on large DB's so again be patient.
