An administrator may need to update the license in use by Zerto Virtual Replication. A warning in the Zerto User Interface is generated when either the license expires or the number of virtual machines exceeds that of the licensed number of virtual machines being protected. Note that protection continues but the license should be updated. After receiving a new license key, you can update Zerto Virtual Replication with this license key.
The Zerto license has expired or the number of virtual machines exceeds that of the licensed number of virtual machines that are being protected.
In the Zerto User Interface, click on the “Site Configuration” icon (three horizontal dashes) in the upper-right corner of the local panel.
In the "License" field, paste the new license.
Note: For an enterprise license, this process will update the license at all paired sites, so this operation only needs to be executed on one site.
For versions prior to 4.0, contact Zerto support.
More information can be found in Zerto documentation.
