The cluster include one Publisher and 2 Subscribers, all server are running 5.1(2b).
Can we upgrade all severs including the Publisher to 5.1(3) at the same time?
Does anyone have this experience?
If I select don't switch to new version, after all servers are upgraded to 5.1(3), I wants to switch to new version at the same time.
Is that correct.
During the upgrade process, I find out all phone registered to the upgrading server do not have any impact during this upgrade process.
