hoping that the password might just be standard and default and match
between old and new. However the reason I suggested using the old
config.xml was to specifically test if it matched the old install or not.
If it didn't match my approach would have been to change the MySQL password
in MySQL to match that which I was used to from the old system - but maybe
that's just how my brain works. I would find learning the new password
annoying.

fine and would probably be simpler. Just need to learn / remember to use
the new one at the appropriate times. Daryl is probably unlikely to have
any custom scripts with the old password hard-coded in?

Other than the password I set up on install I've never used/remembered any
other password. Probably because I have only the one box and don't do
anything remotely.

Thanks for all the contributions thus far. I have another idea I'm
considering, at my disposal is a 250GB drive and two 1TB drives. Eventually
I'd like the OS to be on the 250 and the other two to be set up in RAID.
The question is during this upgrade process can Ubuntu 12.04 and mythbuntu
14.04 be installed in dual boot fashion giving me the flexibility to
continue to record on Ubuntu while I take my time migrating scripts and
tweaking Mythbuntu?

It was a year ago when my son separated the OS from the recordings on the
same 1TB drive for me. How he did it escapes me at this time and what
considerations that will give this new endeavor is unknown to me. My
knowledge is directly related to my experience, so unless I've done
something a couple or three times its foggy at best.

Again, thanks for your time, consideration, and patience.
Daryl.
