Replacing Hardware Appliances with Virtual Appliances

At some point, you may decide to replace one or more of your hardware-based appliances. Replacing either a Web Appliance or Management Appliance with a virtual appliance should be done by following the steps in the order described below.

Note
These procedures only cover the replacement of existing hardware-based appliances with virtual appliances. If, instead, you want to add virtual appliances to use in conjunction with your existing hardware-based appliances, see the instructions in "Grouping Web Appliances" and "Central Management". Virtual appliances integrate seamlessly with hardware-based appliances as well as other virtual appliances.

Replacing a Stand-Alone Web Appliance

If you have a single hardware-based Sophos Web Appliance that you want to replace with a virtual Web Appliance:

  1. Configure the virtual appliance according to the instructions in the Virtual Web Appliance Setup Guide. Take care when configuring the network settings to assign a network address that is different from the hardware-based appliance it is replacing.
  2. If your hardware appliance is not configured to perform automated backups, on the Configuration > System > Backup page, click Download Now. Or, if automated backups are configured, transfer the backed up archive file from the FTP site to the system on which you will be performing the restoration.
  3. On the virtual appliance, select Configuration > System > Restore. Follow the instructions in Restoring a Backup.
    Note
    If your hardware-based appliance was configured to use Web Cache Communication Protocol, you must reconfigure those settings manually on the virtual appliance. WCCP settings cannot be restored from a backup.
  4. When restoration is complete, power off and decommission the hardware-based appliance.

Replacing a Management Appliance

If you have a hardware-based Sophos Management Appliance that you want to replace with a virtual Management Appliance:

  1. Configure the virtual appliance according to the instructions in the Virtual Management Appliance Setup Guide. Take care when configuring the network settings to assign a network address that is different from the hardware-based appliance it is replacing.
  2. Join the newly configured Management Appliance to a functioning Web Appliance in your deployment (not the hardware-based Management Appliance) and copy its configuration data to the virtual Management Appliance. On the Management Appliance, ensure that these check boxes are selected: Allow Web Appliances to join this Management Appliance and Copy configuration and policy data from the first web appliance to join. For complete instructions, see On a Stand-Alone Web Appliance: Joining a Management Appliance.
  3. When the join is complete, power off and decommission the hardware-based Management Appliance.
