I think a lot of stuff was written when 5.3 was announced, that was when
5.x branch was declared "stable" IIRC.

If you have an extra machine or can afford the downtime, then you might
save yourself a lot of work by simply doing a clean install this time.
IIRC this was the "recomended method" for upgrading 4.x to 5.x.

Part the reason I guess is that there has been a lot of reorganizing so
building and installing from src may leave a lot of junk around.

Recently make targets, "delete-old" and "delete-old-libs", have been
added but I'm not sure if that would clean up after 4.x.

I think the major jump is going from 4.x to 5.x, I have since 5.x made
incremental upgrades to 6.x without any problems. So, you might as well
go straight to 6.x and skip 5.x entirely.
