      Description of problem (please be detailed as possible and provide log
      snippests):
      The following problem was specifically encountered during RDR Relocate of a ACM Discovered application, but depending on the accuracy/complexity of the clean up process of an ACM Managed application, it is believed this problem is not specific to Discovered applications.
      During RDR Relocate of an ACM Discovered application, when the corresponding DRPC has .status.progression == WaitOnUserToCleanup, the user must "Clean Up" the application to the point where all protected PVCs are deleted in order for VR and VRG finalizers to complete.
      In this specific case with an application that leverages multiple Operators/Controllers and corresponding CR's, when the protected PVC's were deleted, some Operator/Controller pods were still running and attempting to reconcile application CR's and either re-created a deleted PVC or created a pod that attempted to mount a deleted PVC while the VR and VRG finalizers were running. The result was a stalemated VRG with some protected PVC's as Secondary and other protected PVC's are Primary.
