When you first access the Zerto User Interface, you must register your use of Zerto Virtual Replication by entering the Zerto Cloud Appliance (ZCA) license, or Zerto Virtual Replication Enterprise Cloud Edition (ZVRCE) license supplied by Zerto.

After entering a valid license, the DASHBOARD tab is displayed with a summary of the site.

In order to protect virtual machines to Azure, you must first pair the protected site containing the virtual machines that you want to protect with the Azure site on which you installed the Zerto Cloud Appliance. This is described in Pairing an Azure Site.
