■ (For Hyper-V Environments) VRAs managing protected virtual machines: Either live migrate the protected virtual machines and storage managed by the VRA to another host with a VRA, or upgrade the VRA without migrating the virtual machines and a delta sync will be performed following the upgrade.

■ Upgrading a VRA that manages the recovery of virtual machines results in a bitmap sync being performed after the upgrade. Note that the time to upgrade a VRA is short so the bitmap sync should also be quick.
