Hi there,
When looking at the following link :
Novell Documentation

in the ZENworks 11 SP2 Installation Guide the link takes you too...

Novell Documentation

Which talks about the SP1 installation. Is the upgrade process exactly the same for SP1 and SP2.

It looks like the primary server requirements have been updated to run on SLES sp3 / sp4 so I assume this doc is correct for SP2.
