The Primary role of a volume can be migrated from a Primary node to a Secondary node, within certain restrictions. The process is manual and requires cooperative administrative action on the Primary and all Secondary nodes. During this process, update of the former Primary must be halted and cannot be resumed on the new Primary until the migration is complete.
The Primary role can only be migrated to an up-to-date RLINK that is consistent and is not in an error state. Any out-of-date Secondaries must be fully resynchronized with the new Primary.
