Yes, what you say is correct -- which is why I've chosen a time when I am NOT in a critical production cycle to do the upgrade!

I encountered the problem with four channel output, asked about it other places online and eventually here, and learned that it was due to a kernel bug in the Ubuntu version that I had been running. At that time, I was in the middle of a busy semester and couldn't afford downtime, so I waited until my semester break -- early in the semester break. The concert is not until late September or early October, just shy of three months.

Point being, I didn't do this upgrade on the spur of the moment. I did it to solve a specific problem, I timed it to allow plenty of lead time before the show, and I even installed 12.04 to a live USB stick to test before committing my HD to the upgrade.

Next... the new thread about what I really need. Maybe let's close this thread. Issues with jackdbus in 12.04 have been identified and seem to be the culprit.
