24. Upgrading from NNMi Version 9, 10, or 11

This chapter explains several possible version upgrade scenarios.

For details about upgrading from NNM version 8 or earlier to NNMi, see 26. Upgrading from NNM Version 8 or Earlier. If you plan to upgrade an NNMi management server of version 9, 10, or 11 that is running in an NNMi application failover configuration, the supported upgrade procedure requires you to unconfigure application failover temporarily, upgrade each of the NNMi management servers, and then reconfigure application failover.

To upgrade NNMi version 9, 10, or 11 that is running in a high-availability (HA) cluster, see the Release Notes.
