Migration Nagios 5.8.3 to 2024R1.3.1

[zak_jj]

Hello,

I'm looking how can I migrate my nagios 5.8.3 (RHEL 7) to nagios 2024R1.3.1 (RHEL 9) and I can't found official documentation.

I have a RHEL7 nagios 5.8.3 (prod)
I have a RHEL9 nagios 2024R1.3.1 (already installed and configured, it's the target)

Based on the matrix compatibility I think the steps are like this :
Earliest Hightest
RHEL 7 (EOL) 5.2 2024R1.1.5
RHEL 8 5.7 2024R1.4.1
RHEL 9 5.9 2024R1.4.1

I don't want to touch my actual prod nagios RHEL 7 5.8.3, so :
1/ I export/import all datas to a new RHEL 8 with nagios 5.8.3 installed
2/ I upgrade nagios 5.8.3 on my RHEL8 to nagios 2024R1.3.1
3/ I migrate datas from my RHEL8 to RHEL9 with nagios 2024R1.3.1 already installed

What do you think about it ?
Can you suggest me something else or something better ?

Hey @zak_jj

If you dont want to change the version of your production environment then the route you suggested is the way to go. If you didnt mind upgrading your production enviornment then you can skip one of the migrations steps and upgrade your RHEL 7 instance to 5.9 or newer and then rebuild your RHEL 9 system with anywhere between 5.9-2024R1.0.1 and then upgrade to the version you want to be at from there. I'll add some links to documentation to help with the process.

Slope Game Will the existing check commands, custom scripts, and dependencies on the RHEL 7 system work unchanged on RHEL 9, or do they require updates for Python/Perl or package dependencies?
