I am trying to get my installation to ZCM 11, in order to do this I need to upgrade from 10.2 to 10.3. When doing with the ISO file from download.novell.com I get the following message:

To upgrade to ZENworks Configuration Management SP3 (10.3), you must update
using the ZENworks System Update feature (in ZENworks Control Center, click the
Configuration tab > System Updates).

In the ZENworks Control Center I do not see an update for 10.3, all available updates have been downloaded and installed.

How do I proceed? Blow up the install?
