Nagios Support Forum

Hello,

I need to migrate all my nagios(3.5) and check_mk(1.2.4) settings from a ubuntu 12.04 LTS to a new ubuntu 16.04 LTS server. I have installed
nagios(4.2.1) and check_mk(1.4.0p26) on the new server. How can I migrate my nagios setup? Is it possible to migrate from 3.5 to nagios 4.2.1?

(I just found out with check_mk that I need to install the old check_mk versions in between and upgrade from there, so I need to uninstall check_mk .1.4.0p26, not sure how to do that either)

Thanks!

Kind regards,

I can't make comments on check_mk or mklivestatus. Those individual communities (specifically the mailing lists) are probably a better place to get advice on migration options for those systems:

This post has a sed command that can comment out old Nagios 3 configuration directives in the main nagios.cfg file:

But there's no simple script I am aware of that covers every possible race condition for all of your configuration files. It'll probably be a bit touch-and-go with configuration verifications if you take your Nagios 3 configs and drop them into a Nagios 4 installation.

All that said, if you encounter specific errors when trying to verify configurations in Nagios Core, specific advice can definitely be offered if the problematic config files are shared.

Thanks for the assist, @mcapra!
