my environment:
- ZCM 2017 Update 2a
- 2 Primary Servers, SLES 11.3
- 1 OEM-Sybase database server, SLES 12.3
- 1 Satellite Server with imaging role, SLES 11.3
See the ZENworks documentation that refers to Primary Servers:
If ZENworks is already installed on the system, do not perform a major in-place upgrade of the operating system (for example, from SLES 11 SP4 to SLES 12) as this might cause issues and the Primary Servers might have to be replaced.
I couldn't find anything related to satellite servers, but I want to upgrade the satellite server from SLES 11 SP3 to SLES 12.3. Any recommendations? Should I upgrade or migrate?
