Upgrading newbie

We haven’t upgraded RT since installing V3.0.7_01 in Oct '03, and I’d like
to upgrade to take advantage of all the changes since then.

The instructions are pretty clear.

I have a really stoopid question though: prior to upgrading, am I supposed
to move my existing RT tree out of the way, say from /usr/local/rt to
/usr/local/tmp; then put the new RT tree at /usr/local/rt, test (and fix)
dependencies, make upgrade, update db, copy my good RT_SiteConfig.pm back
in?

Thanks.
