Server Edition software supports several methods for upgrading. For virtual machines, the supported method is to upload the new ISO file to the virtual server, using one of the methods below, and then select upgrade within the IP Office Web Manager menus.
Method
Summary
Transfer from a virtual DVD
Upload the ISO file from a virtual DVD drive. You can connect an ISO file to the virtual machine's DVD drive in several ways.
Transfer from a remote file server
Upload the ISO file to the server from a file server (http, https, ftp, sftp or scp).
Transfer via SSH/SFTP to the virtual machine
Upload the ISO file directly to a folder on the server using SFTP.
Direct transfer
Upload the ISO file to the server using the IP Office Web Manager browser session.

Not Supported for Upgrades from Pre-R12.0:
This method of upgrading is not supported for upgrading from pre-R12.0 releases. For example, from R11.1 to R12.0.You must upgrade the server using the processes in the Upgrading Linux-based IP Office Systems to R12.0 manual.
WARNING: Boot from DVD Upgrades:
For non-virtual IP Office servers, the server can boot from a DVD copy of the ISO. The menu presented includes an option to upgrade. However, for virtual machines this method of upgrading is not supported.
In a Server Edition network consisting of several servers, you can use IP Office Web Manager to first upgrade the primary server. The files on the primary are then used to upgrade its associated secondary, expansion and application servers. Note that this is not possible from a newly installed virtual primary server.
The VMware Snapshot feature can be used to provide a more robust upgrade process by providing a fall back point to the previous instance of the virtual machine. See VMware Features.
