Platform Upgrades - Northern Telecom NAC Installation Manual

Platform upgrades

If you are currently running a NAC 1 system and want to upgrade your
operation to a NAC 2 system, a platform upgrade is needed. Use Procedure
9-1 to complete a platform upgrade from NAC 1 to NAC 2.
Ensure that all of the hardware installation is complete before proceeding
with the software installation.
Before starting any upgrade, verify that the system is performing properly.
Check the NAC error log and the UNIX system log (when appropriate) to
verify that midnight backups are successfully completed. Schedule an
upgrade to be completed before 11:30 p.m. or started after 1:00 a.m. so that
the regular NAC midnight routines are executed properly.
Note: Because you are performing a platform upgrade, no port
assignments are retained from your NAC 1 system. Therefore, all
system ports must be reassigned.
