[rt-users] Upgrade to 2.0.13 .. step by step?

[RT2 Troubles]

So here's what I can gather for instructions on upgrading 2.0.11 to 2.0.13 
and I'd like some feedback before I go ahead and try it:

Download the rt.tar.gz
tar xzvf rt.tar.gz
cd rt-2-0-13
vi Makefile
  - change all options that are different on your install
cp /path/to/rt2/etc/config.pm /etc/config.pm.backup
make upgrade
vi /path/to/rt2/etc/config.pm
  - reconfig based on the old backed up config
/etc/rc.d/init.d/httpd restart

Done?

No stopping of services, no recompliing of Perl, no dependency hunting?
Could it be that easy?
