NCD – Upgrading the Zerto Virtual Manager (ZVM) Service and Virtual Replication Appliances (VRAs)
The Zerto Virtual Manager (ZVM) is a management and control console Windows® service that runs on a Microsoft® Windows virtual machine (VM) within a vCenter environment. In order for a customer site to be able to pair with a Navisite Cloud Director (NCD) site for disaster recovery, a single ZVM must be installed and configured at each site managed by a vCenter Server.
When upgrading the ZVM service, the Virtual Replication Appliances (VRAs) that were installed in the previous version are not upgraded automatically. It is recommended that you always upgrade the VRAs to the latest version on your site.
Important: Before performing these upgrades, it is recommended that you create a vCenter snapshot of the Windows VM that hosts the ZVM in case it becomes necessary to revert back to your original configuration.
Before performing these upgrades, all Virtual Protection Groups (VPGs) should have a status of "Protected."
To upgrade the ZVM service and VRAs:
- Open a console session to the Microsoft Windows VM hosting the ZVM service.
- In the console session, open a web browser and navigate to:
