Migrating to new server on different distribution.

[grant.bakken]

- In light of the CentOS8/Stream announcement.

nutshell overview- we have an older NagiosXI install running - it predates me at the company but I believe it is the appliance from Nagios based on CentOS 6.

we have 740-odd hosts and about 1600 service checks configured. we currently have version 5.6.9 of NagiosXI in place.

what are the options, and by what process would be best practice to migrate this configuration to a new install? what would be the recommended Linux distro? We have to date mostly kept with CentOS, and for some things will more than likely land on RHEL but we aren't tied hard to RH or it's derivatives.

Thanks!

Hi Grant,

The good news here is that we support a wide variety of Linux Distros for XI - RHEL, Cent, Ubuntu, Debian and Oracle Linux. We haven't fully tested and rolled out support for Cent Stream, so Ubuntu 20.04 is a good choice for a new deployment ( or RHEL 8) right now.

For a standard installation (without customizations) the backup and restore scripts will do all the heavy lifting to migrate from one instance to the other. It's best to install the older version on the new server, migrate and then upgrade to the latest.

The Nagios XI license allows for 3 activations, so you can safely set up a test sever with the new OS installed, migrate and then roll it over to production once you're ready to go.
