5 Upgrading NOAM

The NOAM upgrade section is common to all topologies. This section must be completed before executing the site upgrade procedures. Procedures for the NOAM upgrade include steps for the upgrade of the Disaster Recovery NOAM (DR NOAM) servers also. If no DR NOAM is present in the customer deployment, then the DR NOAM-related steps can be safely ignored.

Global Provisioning is disabled before upgrading the NOAM servers. Provisioning activities at the NOAM and SOAM servers have certain limitations during the period where the NOAMs are upgraded and the sites are not yet upgraded.
