3. If using ESSs, upgrade Communication Manager on the S8500 or S8700-series ESS to the
latest version.
4. Upgrade Communication Manager on the S8500 or S8700-series primary controller to the

Upgrade of Communication Manager on the S8300 LSPs and ESSs, if any
For more information on S8300 LSP upgrades, see Installing and Upgrading the Avaya G700
Media Gateway and Avaya S8300 Media Server (555-234-100).
Note:
Note: An LSP does not accept translations if it is running a version of Communication
Manager that is older than that of the primary controller. However, the LSP
remains registered with the primary controller,
You might use the Upgrade Tool, available on the Web pages of the primary controller, to
upgrade Communication Manager on all the LSPs and ESSs. However, to use the tool, the
following files must be resident on each LSP and ESS:
● Communication Manager
● Authentication file
For more information about using the Upgrade Tool, see Job Aid: Upgrade Tool and
Worksheets, 555-245-757.
Stopping and starting LSPs
Before you upgrade the S8700-series Media Server, you might want to stop call processing on
the LSPs. This stoppage allows the media gateway and IP telephones to quickly reregister with
the primary controller after the upgrade.
If you stop call processing on the LSPs, you must restart them when the primary controller
upgrade is complete. In addition, the stoppage of call processing on the LSPs has the following
consequences:
● During the interchange between the active and standby media servers, analog and digital
telephone calls are dropped.
● New calls to or from IP telephones cannot be made during the interchange.
● If the upgrade has problems so that service from both servers is lost, all telephones go out
of service. This outage includes telephones assigned to backup service on the LSPs.
