I have an mysql cluster which have 4 data nodes and number of replicas is 2. So I have 2 node groups with 2 data nodes in a every node group.
I planing to add 4 data nodes more to this cluster. After adding nodes i can reorganize partitions but I have to do this for every table.
Is it possible to restore a backup which was created from 4 data nodes to cluster that have 8 data nodes?
