I recently upgraded lots of hosts from 4.10 & 4.11 & 5 & 6 to 7.2,
So many to keep track I needed my
I `just' moved in the binaries from CD alongside, flipped the directory
contents, rebooted, then built new custom kernels & make world & rebuilt
But I didnt do some cross compile from 4 to 7, too much like hard work that!
So quite possible to upgrade without repartitioning disc
& reloading data. But you might want a bigger root. You might want
a newer FFS for performance (can't remember when that came in).
... there'll doubtless be a few other `Gotchas' so if you have problems/
not enough experience/ get stuck. the safe way is a back up, & reinstall.
Well, a back up's not exactly a foolish precaution anyway ;-)
