Re: Procedure for moving a Repl set from one CG to another RP SE 5.1
The process entails removing the replication set from the current CG - this will have no impact. Afterwards, add the replication set to the relevant CG, this will not involve journal history loss but a volume sweep would occur. Note that this should be relatively quick as little data would be replicated over the wire granted the existing replica volume is selected when adding the volume.
Hope that helps,
