Currently we have two primary servers ZENworks 2017 Update 1 with SLES12SP2.

As ZENworks Update 2 bring SLES12SP3 support we have a few questions:

1) After ZENworks Update 2, is it best to upgrade the OS of the primary servers from SLES12SP2 to SLES12SP3?

2) We are going to install satellites with ZENworks Update 2 , which OS should we take SLES12SP2 or SLES12SP3?
