Can anyone direct me to some good documentation specific for upgrading
from ZEN 4 to ZEN 7?

I have read the documentation and knowledgebase and find little to help
me. Everything talks about the upgrade from 6.5 to 7 - not what I need.

I need to upgrade 3 modules, workstations mgmt, imaging, and app launcher.

Any help/advice/direction wil be greatly appreciated.
