Notifications, Messages, and Resiliency configuration information are not upgraded
During the upgrade from a pre-NetBackup 10.0 environment to NetBackup 10.0 and later, previous notifications, messages, and Resiliency configuration information is not migrated. Any previously added Resiliency Domains are no longer present on the Resiliency tab in the NetBackup web interface.
You must reconfigure after the upgrade completes to rediscover the resiliency domain data. Refer to the referenced tech note for additional information on how to reconfigure VRP after upgrading NetBackup to 10.0.
