Upgrading R9csi/R10csi/Communication Manager 1.x/2.x to Avaya Communication Manager 2.2 on an
206 Installation, Upgrades and Additions for Avaya CMC1 Media Gateways
Customers upgrading to Avaya Communication Manager can migrate to the 6-/7-digit dial plan
or not:
● Customers who want to migrate to the 6-/7-digit dial plan can
- freeze their translations and send them to Remote Technical Services (RTS) for
conversion. For customers who do not have optical drives, Avaya must migrate those
translations to customer-compatible media.
- re-administer the switch themselves (no translation freeze required).
● Customers who do not want to migrate to a 6-/7-digit dial plan (want to keep their current
4-/5-digit dial plan) experience no changes after the upgrade. That is, if they had 4-digit
dialing before the upgrade, they have 4-digit dialing afterwards.
Service interruption
The upgrade process requires a non–call-preserving service interruption in a standard reliability
system. The service interruption must be closely coordinated with the customer and the local
account team. The service outage for standard reliability is 2 to 15 minutes, depending on the
size of the installation.
Call Management System (CMS)
The CMS link is dropped and restarted during the upgrade, causing:
● Loss of CMS data. To minimize the measurement data loss, perform the upgrade just after
the last CMS measurement interval. If needed, print the reports before starting the
upgrade.
● Dropped calls (call processing aborted) if a measured trunk that was part of the
conference dropped off the call before the end of the call. Customers experiencing this
symptom and who are running R3V4 CMS should update to r3v4ao.e or higher.
Software compatibility
Before starting the upgrade, always check the Software Release Letter that accompanies the
system removable media. Translation corruption occurs if incompatible software is loaded. Also
check the Minimum Vintage Table, which is included with the letter, before starting the upgrade.
