We are running NNM 9.005 in app failover with dedicated isPI performance for metrics. Now, we are planning to upgarde NNMi from 9.0 to 9.20. This would also involve upgrade of iSPI to version 9.20.
iSPI server is running on Windows OS 2003. We need to format this iSPI server and install Windows 2008 as per the application requirement.
Please suggest on below;
Can we do a fresh install of iSPI 9.20 and then restore backup from the 9.0 version. OR we should first install isPI 9.0 on the windows 2008 server. then restore the backup . After the backup is successfully restored, we should upgrade application to version 9.20.
Also, please suggest
If all configuration, data and customised extension packs would automatically be migrated from the old server backup to the New server after backup restore.
What additional steps would be required for this upgrade.
Any known issues and challenges with this type of upgrade.
