Cutting Over To S8700 Or S8710 Media Server Control; Completing The Migration; Testing The S8700 Or S8710 Multi-Connect Configuration - Avaya S8700 Series Manual

This stage is service affecting for the PPN and, thus, the existing DEFINITY ECS system. It is
out of service while the carriers are changed out, which should take no more than 30 minutes.

Cutting over to S8700 or S8710 Media Server control

Once the PPN is converted and you power it up, you want to cut over to the S8700 or S8710
Media Server. To do this, you must enable the IPSIs on the IP Server Interface (IPSI) System
Parameters screen.
This stage is momentarily service affecting as the CSS comes back up and the calls are
load-balanced across the IPSIs throughout the port networks.

Completing the migration

This stage includes verifying the customer's data and upgrading IPSI firmware (if necessary).
Alarms are generated if the IPSIs do not have the most current firmware or do not all have the
same firmware.
For information on other post-migration tasks, such as clearing alarms, backing up the media
servers, enabling alarm reporting, and registering the system, see Installing and Configuring the
Avaya S8700 Series Media Servers (03-300145) and go to the "Completing the installation
administration" section.
This stage includes clearing alarms, upgrading IPSI firmware (if necessary), backing up the
media servers, enabling alarm reporting, and registering the system. Alarms are generated if
the IPSIs do not have the most current firmware or do not all have the same firmware.
This stage must be performed after the actual cutover. However, some parts of this stage
(upgrade firmware, register system) could be done before the cutover.
None of the operations performed in this stage is service affecting. However, if during alarm
resolution hardware needs to be replaced, it could result in a service interruption.

Testing the S8700 or S8710 Multi-Connect configuration

This stage involves testing the complete system and verifying proper operation. Functional call
processing is tested, such as station-to-station calls, outgoing calls, incoming calls, and so forth.
Various hardware-related testing procedures are provided. These may or may not be
performed, depending on whether a given piece of hardware is configured.
Perform the testing procedures after the actual cutover is completed and while completing the
migration.
These procedures are not service affecting. However, replacing hardware to resolve problems
encountered may be service affecting.
