upgrading ZCM 10 to 11

I have ZCM 10.3.3 installed in a VM using the ZCM appliance. It is
currently running SLES 10 SP2. This is a relatively small
installation, so everything runs on a single server and it uses the
embedded database. I do have one satellite server at a remote office.
Is there a recommended method for upgrading the appliance install to
ZCM 11? Or is it just a matter of applying SLES 10 SP4 and then
running the ZCM 11 upgrade?
