This is the part I hate most about these upgrades. All options result in 
downtime.
* Bite the bullet and upgrade "production" system. Do a backup first, in 
case new system doesn't work too well.
   Problem: if I run the new system for a month and then decide it's not 
ready for me yet, all the work I've done in that month will need to be 
migrated back into the old install.
* Install on 2nd HD/computer to see how it handles/etc. In this case, I 
have to take time to boot into 2nd environment and play around, then 
boot back to prod to do my work. Too much time wasted in "new" environment.

What I'd really like is incremental changes instead of upgrades - kind 
of how linux moved away from the "new version" approach.
Of course that's not so easy with a large distribution like this. But 
maybe it's doable.
