just this week, i moved from f17 -> f21.

i found most config stuff under /etc for host and all /home/jackc for the rest.
i slammed these to an offline drive, copying homdir back after the os was ready.

naturally, YMMV...

The recommendation is to go through successive upgrades one after the other. However, I am very doubtful that one of these will not break. I seem to recall that F18 or F19 was the one which broke upgrades (I think it was F19).

I don't see why this should be an issue in a clean install. Are you wanting to keep /usr because you installed programs here? You may consider moving files that you created to a separate directory inside your home partition and then pushing it back. One possibility is to partition the current /usr and then move the programs to that new partition and keep that one in a new install.

I am not sure how RAID0 figures into this equation: I have not much knowledge of this, sorry.

You can pretty much preserve whichever partition you want as long as it makes sense. For instance, you could keep a separate /usr/local partition where you could put your local installed programs. But this is after the fact so will not be helpful.

It is for situations such as these that I wish that there was also a rolling-release version of Fedora.
