20.4.3 Back up data before upgrading NNMi or the operating system
Before making major system changes (including upgrading NNMi or the operating system), perform a complete backup of all NNMi data. To ensure that no changes are made to the NNMi database after the backup is made, stop all NNMi processes and create an offline backup.
Example:
nnmbackup.ovpl -type offline -scope all -target nnmi_backups\offline
If NNMi does not run correctly after the system change, roll back the change or set up a different NNMi management server and ensure that the requirements listed in 20.3.2 Different-system restore are satisfied, and then run a command similar to the following example:
Example:
nnmrestore.ovpl -source nnmi_backups\offline\newest_backup
Update the licensing as needed.
