After VMs are migrated to another site using the disaster-recovery or planned-migration features in SRM, they are in an active running state on the network at the alternate site. However, they are vulnerable to a site failure with no SRM protection. Previous versions of SRM required a manual reprotection of the VMs at the recovery site. Today, SRM automates the reprotection process and prepares the virtual machines for failback.
