If by "export - import" you mean, do a complete backup of the database ( 
http://www.mythtv.org/wiki/Database_Backup_and_Restore ) and then do a 
full restore of that backup on the new machine, replacing whatever 
database may be there ( 
), that's the proper procedure for handling the database.  As Nick 
mentioned, make sure you consider host names--the easiest approach is to 
use the exact same host name for the new system as you used on the old, 
since all your configuration is stored in a profile based on the 
system's host name.

And, IMHO, rsync is the best tool for moving the recordings themselves 
(using --progress, especially, makes it user-friendly--not to mention 
the fact that you can stop/restart it as necessary).
