(I think you mean http://www.mythtv.org/docs/mythtv-HOWTO-23.html#ss23.5 
--it's easy to get the wrong link since the section titles link back to 
their location in the table of contents :)

Mainly just remember that the backup is only a backup of the database 
data--you'll need to ensure you handle the upgrade/reinstall such that 
all recordings files stay intact.

There have been a few updates to the backup/restore scripts in trunk 
that aren't in the -fixes version, so you might want to download the 
newer versions (see 
http://www.mythtv.org/wiki/Database_Backup_and_Restore for details on 
how to download them).  The updates are mainly additional safety checks 
to prevent problems caused when users forgot steps or whatever (so 
they're good for ensuring you do things right).
