Adding new nodes to HA cluster

Not sure you can mix & match 11.2 and 11.3... But if you can, I'd update to 11.2.1 first as the clustering is a LOT better in 11.2.1 than 11.2.0... I don't think I ever got 11.2.0 down to where it worked for me without problems across >2 devices. (11.2.1 though I have a 6 device cluster on one of the installations, and that seems pretty good apart from the odd stupid moment where one of the devices just won't take a sync because it thinks its in the middle of SENDING to the group... That one requires a reboot more often than not, but I have seen it magically wake up to reality after 2 days of just sulking).
