3.8 Recovery Procedures Overview

These procedures are customized to the specific situation encountered and therefore do not have well-established time frames. The order of the back out for the primary NOAM NE and DR NOAM NE needs to be followed as shown in the following table.

Note:

Backout is not supported if the upgrade was performed from 8.x to 9.x release

Note:

During back out of servers, there are steps to check the replication status before going to the next server back out. Follow the steps to perform; otherwise, it may result in data loss.

Note:

During the back out some alarms/events may be raised that can be ignored. Alarms are mentioned in step 4 of Health Check Procedures.
