[mythtv-users] How to upgrade?

[Cliff Avey]

I apologize if this question has been asked before. Could you folks 
point me to some info about how to upgrade my MythTV while preserving my 
library of pre-recorded programs? I have an ancient version (0.18 on FC3 
with a 2.6.10 kernel, client/server setup). I assume I also need to 
upgrade my Linux. Problem is, I don't have enough hardware to build a 
2nd server, and it records almost every day (at least it will until 
Zap2It shuts me off and I can't switch to SchedulesDirect), so I need to 
to upgrade quickly while preserving as much data as possible.
