Nagios upgrade path to latest version

[marcmooney-atos]

Hi,
I currently have CentOS Linux release 7.6.1810, which I believe needs to be upgraded to CentOS Stream 9 for latest version of Nagios? Is this correct?
Current Nagios version that we have is 5.5.9. Is there a specific upgrade path or can I upgrade directly from this version to the latest?
Thanks.

Hello @marcmooney-atos,

You can find instructions on how to upgrade here: Best Practices for Upgrading Nagios XI

We recommend setting up a new Linux system/image with CentOS Stream/RHEL 8/9 (if you decide to stay with CentOS/RHEL) as a new server. Then install the same version of XI that you are running on the current production system. Once installed, you should be able to replicate your configuration through the backup and restore process (document below) by backing up your current XI configuration and restoring it to the new system.

Depending upon the version of XI you currently have installed you may need to upgrade your version of XI to a newer version before migrating. For example, if you are running XI version 5.4.13 on CentOS 7, you will need to upgrade to at least 5.7 before migrating to CentOS Stream/RHEL 8 and XI version 5.9 before migrating to CentOS Stream/RHEL 9. You can use the compatibility matrix in the documents below for assistance. And make sure you perform the upgrades on a test/trial instance so that you do not disrupt your production environment. Contact your Customer Success Manager ([email protected]) for a temporary trial key and a temporary increase in allowed activations.

So here, I would recommend upgrading to a version of XI 5.9+ that supported CentOS 7 and then migrate your instance of XI to a CentOS 9 machine with the same version of XI, which can then be upgraded as far as you like.
