hi team,

I have 10 node cluster, I upgraded from 10 nodes to 2 nodes now 1 node is master node . Do I need make master node to other node and then upgrade 1 st node or I can directly upgrade the master node.

You can directly upgrade the current master, and when it restarts, another master should be elected.

yes I have other 2 nodes as a master eligible, so if master node go down than any of other 2 node will become master right?
