Re-Registering a Virtual Appliance

If you clone a virtual appliance, each cloned instance must be re-registered before you can use it in live production mode.

Re-registration is necessary to take advantage of reporting and clustering features. If you do not re-register a cloned appliance, it cannot be distinguished from the parent appliance (the virtual machine it was cloned from) if both are used on the same network; properties such as the hostname and static IP address are identical to that of the parent virtual machine.

You can re-register a virtual appliance on the Configuration > Network > Network Interface page. Alternatively, you can use the command-line interface of the virtual appliance, which is available via the Console tab of your VMware client. See the Virtual Email Appliance Setup Guide for more information.

Important

If the appliance you plan to clone belongs to an existing cluster of appliances, you must remove it from the cluster before cloning. Once you have cloned an appliance and re-registered it according to the steps that follow, you can join one or both of the appliances to the cluster.

Before re-registering, ensure that you have configured unique network and hostname settings for the cloned virtual appliance. See the Virtual Appliance Setup Guide for more information.

If you have configured certificates for the appliance on the Configuration > System > Certificates page, you must upload new certificates that bear the hostname of the cloned appliance. This is not necessary if you are using the default self-signed certificate.

To re-register a virtual appliance:

  1. Click Re-Register.
  2. In the Re-Register Cloned Virtual Appliance dialog box, You are prompted to erase duplicate data that has been copied to the cloned virtual appliance from the original image. Doing so removes duplicate logs, reports, and message store data. If you want to do this, select Erase duplicate data.
    Note
    Before re-registering, ensure that you have configured unique network and hostname settings for the cloned virtual appliance. See the Virtual Appliance Setup Guide for more information.
  3. Click OK.
    When re-registering is complete, you are returned to the Network Interface page, and the status is displayed at the bottom of the page.
