It couldn't hurt to upgrade to the latest KiX version too. I would, however, verify with the "pros" about any compatibility caveats that might arise from the upgrade.
The physical steps to upgrading, however, couldn't be simpler (if you're on a winNT - 200x network (no 9x))
Just download the newer version and call the newer version's .EXE from your batch file or your user's logon script field (which ever you're using)
