I doubt anyone can give such an assurance.

In cases where it's "mission critical" then your answer is to have a 
test system. Clone you live system to the test system, then test the 
upgrade there. If your test system upgrade goes OK, then do the same 
on your live system.

Obviously making sure you have a completely up to date clone of your 
live system will allow you to revert to how you were if it all goes 
pear shaped. That can be as simple as shutting down the backend and 
MySQL etc, then cloning everything but your recordings to either 
spare space on your recordings disk or to another disk. There are 
many tools to do this, my personal favourite being rsync.

So the process is :
1) Determine what you are going to do, and how you are going to 
recover if it goes wrong.
2) Test it on a test system - which should be as close as possible in 
setup to your live system.
3) IFF that test goes OK, then upgrade your live system.
4) And if that goes wrong, revert to how you were.

This should be the minimum for any upgrade on anything that you don't 
want to risk losing. Yes it can be a pain, but I suspect the pain in 
your ears if you "break TV" can be worse !
