fwiw, I recently ran the Feisty upgrade on my Edgy frontend/slave backend, which is also my beater. Really didn't expect it to work since the Edgy install was more than a little abused by a year of tinkering.
Fully expected it to bomb but Myth never missed a beat.

Upgraded moms bone stock (non Myth) Gutsy to Hardy and the only glitch was a known bug (which I'm at a complete loss to remember what it was atm, old age and crs sux!) that affected minor things like accessing Synaptic, etc.
The fix was a simple copy and paste a single line into a file that's really hard to get write access to but once done, everything worked fine.
...Didn't even require a restart (although I have no idea how that's possible) but uname -a showed the new kernel so, wtf?

So... Backup, backup, clone, backup.
If the upgrade goes sideways well, plan B was fresh install anyway.
