Hi there,

I have 4 SLES 11 servers to upgrade from ZCM 11.3 to ZCM 11.4 and then from ZCM 11.4 to ZCM 11.4.1

I only have a short timeframe in which to complete these upgrades on all 4 servers and do testing.

Do all servers have to be upgraded to the same version at the same time.

If the services remain off on say two of the server and the main primary and one other is upgraded,
can the remaining two be upgraded a few days later.

I't just worried I will run out of time during our maintenance slot to complete all the work.
