Re: [EXTERNAL] Moving a 4 node cluster in two pairs?

why not vol move everything to one pair, then remove the other pair from
the cluster.
make a new 2-node cluster, snap mirror everything, then ship.
then re-make the 4 node cluster once you safely arrive at the destination.

or, ship the temp 2-node pair first, *then* snapmirror everything to it
(requires a decent WAN)
so the data is known safe at the destination before you move the origin
cluster.
