You can build your own standalone perl without touching the system
perl using something like perlbrew http://perlbrew.pl

If you're planning to upgrade in-place, keep in mind that the
UPGRADING.mysql step (more below) generally takes a while.  We almost
always recommend working on a new machine or VM for a larger upgrade.
It allows you to test the upgrade and find out how much downtime
you're going to need.

If you're planning to upgrade in-place on that mysql, then you do not need
to dump and restore, but I'd make *really* sure that my backups were
sound before doing so.
