Note: Virtual Host Names and IP Addresses Unnecessary for Single Servers

This version of the Polycom RealPresence DMA system eliminates the need for virtual host name(s) and IP addresses in a single-server system. When a version 5.0 or earlier single-server RealPresence DMA system is upgraded to version 5.1 or later, the previous version's virtual host name(s) and IP addresses become the upgraded version's physical host name(s) and IP addresses, so accessing the system doesn't change.

(Exception: If only IPv6 is enabled, the system must have two addresses, so a single-server system must still have a virtual host name and IP address.)

The following table describes the parts of the Software Upgrade page.

Field	Description
Version Information	Shows the current system version and the rollback version (if any), which is
	the previous system version.
Upgrade Package Details	Shows the version number and other information about the upgrade file that’s
	been uploaded (if any). Also indicates whether the system must be restarted
	after upgrading and displays a brief description, which includes an estimated
	install time.
Operation History	Lists each upgrade management operation (upgrade or downgrade), showing
	the server on which it was performed, package version, date of the operation,
	and which user performed it.
