Hello Experts I need to migrate an existing 3 node Zk ensemble to a different set of servers in a different networkSo servers A,B,C move to D,E,FWhat is the best way to do that without causing affecting the service This is is what we have been planning1. Add one node from the new network 2. Join and sync up 3. Remove one from the old network4. Do this for all the 3 nodes OR 1. Add 2 nodes in the new network2. Join and syncup3. Remove 2 nodes from the old network4. Add the 3rd node in the new network5. Make sure it is the leader ( a restart maybe ?)6. Remove the last remaining node from the old cluster The second option i would hope would ensure the leader stays in the network with most nodes and avoids problems due to network partitions ?
