Upgrading Antivirus on SBS 2003 Help

I am fairly new to SBS 2003 so I am being extra careful when updating and installing programs. I just have a quick question about upgrading our antivirus.

We are currently using Symantec w/groupware protection. We are running version 10.1 but need to upgrade to 10.2. Are there any SBS 2003 issues I need to be aware? Should I be able to upgrade without it affecting anything?

FYI – I took over for an outsourcing company so I am playing catch up on a lot of things here. We don’t even have SP1 installed for SBS 2003 yet. I just received my SBS 2003 CDs so now I can plan for that install.

Any tips..ideas..thoughts.. I would really appreciate it.
