Upgrading R9csi/R10csi to Avaya MultiVantage
Software on an Avaya DEFINITY Server CSI
7-digit dial plan expansion
The upgrade automatically converts the old Uniform Dial Plan forms to the new
forms. These forms are discussed completely in the Avaya MultiVantage Software
Administrator's Guide.
Customers upgrading to Avaya MultiVantage Software 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 the TSO for conversion.
— 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.

Issue 5 October 2002
For customers who do not have optical drives, Avaya must migrate
those translations to customer-compatible media.
