Hi [NAME], 1. Yes, you can certainly failover/test using the target side vRPAs using the plugin on the other vCenter 2. RP4VMs would try to replicate back upon failover and would auto-replicate once the prod site goes back up again. You can pause transfer upon failover to prevent that transfer as needed 3. You can certainly create a group set with all CGs and then perform a failover against that group set, it's highly recommended to test and make sure the PiT (Point-in-Time) is valid and move backwards/forward in time until the right PiT is selected and then failover to it. Once failover commences, there is no option to pick a different PiT 
hello, we use RP4VM 5.3 and all works well. Ich have a few questions in case of disaster: We have 2 Sites. Each Site has its own ESX Cluster and Storage System. Both Sites use the same vCenter hosted on a third Site. Best reguards, Matthias
