upgrading Nagios OVA

[wjoyner]

My current Nagios OVA is on CentOS release 6.10 (Final) and Nagios xi Installed Version: 5.6.12

What OVA would I download to get on the latest version of Centos and migrate my current xi version over?

Any help would be appreciated.

Hello @wjoyner

Thanks for reaching out, there are other options out there, and want to provide guidance on a potential starting point.

The option to temporarily install a new server running EL7/EL8/ latest, then install the Nagios XI version 5.6.12 to match and migrate over to your temp server and then go ahead and run the Nagios XI upgrades from:

• xi-5.6.12 to xi-5.6.14
• xi-5.6.14 to xi-5.7.1
• xi-5.7.1 to xi-5.7.3
• xi-5.7.3 to xi-5.8.0
• xi-5.8.0 to xi-5.8.2
• xi-5.8.2 to xi-5.8.4
• xi-5.8.4 to xi-5.8.6
• xi-5.8.6 to xi-5.8.7

Once you completed the upgrade on the temp stand-up, migrate the Nagios to the spun-up of the latest OVA.

Here is the outline of the migration.

The XI backup/restore process makes this pretty easy:

- Install the same version of XI that the old server has on the new server, no need to configure it, just install it and go through the initial setup (do not try to restore over different versions of XI you will cause issues)

- If you have a RAMDisk installed, are using RRDCacheD, or are running Mod_Gearman on the old system, set them up before restoring:

If you are monitoring vmware/oracle you'll need to reinstall the proper supporting packages on the new server again following these guides:

- Backup the old/transfer to new/restore to the new

- Follow the After The Restore section from the backup/restore guide completely

- Since you're changing OS versions, run the restore_repair script from the backup/restore guide

- Shutdown (or re-IP) the old, set the old IP on the new system so you don't have to update agent configs/FW rules

That's pretty much it. Please be aware of what a single XI license entitles you to:

Then apply configuration and upgrade the new server to the latest XI version.

If your current system is 32-bit you need to follow this as well to migrate the performances, if it's 64-bit already, no need to follow this:
