Upgrading or Reinstalling Microsoft SCVMM/Hyper-V Components (Hyper-V Environments Only)

Refer to Microsoft documentation for complete information regarding installation and upgrading of Microsoft products prior to installation or upgrade.

Verify that your version of Zerto supports the new Microsoft version before beginning the installation or upgrade.

See the Interoperability Matrix for All Zerto Versions for the list of Hyper-V environments supported by this version of Zerto.

Reinstalling VMM

If you need to reinstall the VMM, including rebuilding the database, contact Zerto support for help throughout the re-installation.

Upgrading or Reinstalling a Host

When upgrading, including applying patches, or reinstalling a host with an active VRA:

1. First, change the recovery host of every virtual machine in every VPG that recovers to this host, to avoid a Delta Sync after the host has been upgraded and the VRA started up.
2. Then upgrade the host. You can move the virtual machines to a different host from within the Zerto User Interface, as described below, or by using cmdlets, as described in Zerto Virtual Replication PowerShell Cmdlets Guide.

To change a recovery VRA:

1. In the Zerto User Interface, click SETUP > VRAs.
2. Select the VRA to change and click MORE > Change VM Recovery VRA.

The Change VM Recovery VRA dialog is displayed, listing all the virtual machines being recovered on that host.

3. Review the list and select the virtual machines to change the target host to another specified target host.
4. From the Select the replacement host drop-down list, select the target host for these virtual machines.

You can move some virtual machines to one replacement target host, and then by repeating the operation, you can move other virtual machines to a different target host.

Validation is performed to make sure the selected target host can be used. For example, the datastores used by both the VRAs are accessible from both hosts.
Any implications of the change, such as whether synchronization might be required after the change is also displayed.
5. Click SAVE.
During this procedure you cannot edit the affected VPGs nor attempt a failover, move, failover test, or clone operation.
At the end of the procedure a Bitmap Sync might be required to resynchronize the protected machines with the recovery VRAs.
Upgrading Integration Services

You do not need to upgrade Integration Services on a VRA.

Restarting Zerto Virtual Manager After SCVMM Upgrade

Zerto Virtual Manager must be restarted after SCVMM is upgraded.
