After protected VMs are migrated or failed over to the secondary site as part of disaster recovery, the VMs are unprotected and are no longer replicated to a recovery site. Following the migration of protected virtual machines, SRM enables automating the reprotection of the VMs. The reprotection is carried out in a series of automated steps, as shown in Figure 17.
During a reprotect, SRM commands the SRA to start storage replication for each of the datastores or volumes in the protection group. This action occurs in the opposite direction compared to the replication topology before the failover. The protection group that was originally set up at the primary site is migrated to the secondary site. Placeholder VMs that were originally set up at the secondary site are now created at the opposite site (the new recovery site) on its respective placeholder datastore (Figure 18).
