[otrs] Upgrade 2.4.3 to 2.4.4

Hi Everyone, Simple question really, I've got OTRS 2.4.3 installed and wish to upgrade to 2.4.4, what is the procedure for this? I can see there are instructions for upgrading from previous versions (2.3.X) but not from 2.4. I have it installed on Fedora Core, although I'm a bit new to Linux. Is it a matter of doing a yum update (will this retain system settings?)/extracting files from the tarball? Thanks, David
