Upgrade Nagios from 5.4.9 to 5.8.2

[Aldo Lanfranconi]

Hello

I am planning to upgrade my current NagiosXI Installation, but doing the automatic update by the GUI fails, an by command line i got an error saying tha the current CENTOS version is not supported any more.

I have NAGIOSXI installed on a VMware VM, created for an .ova file dowloaded from you website.

What are the steps to upgrade it?

Thanks a lot

Hi,
The XI backup/restore process makes this pretty easy.

The process is this:
- Spin up new server running EL7/EL8 latest

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

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

- 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:
