Nagios Support Forum

Hi All,

I am looking for advice on the best way to upgrade my Nagios installation (or whether I should keep it as is). I am currently running Nagios 2011R3.2 on Centos 6.2. I originally downloaded and installed the virtual machine setup with this version and haven't done much updating at all of either Nagios or Centos. I don't think I've added many external commands / libraries / packages but don't really remember.

So, as near as I can tell my options are

1. upgrade the existing Centos to 6.4 and Nagios to 2012R2.2 in place,
2. download the latest VM and do a backup of the existing nagios system and restore to the new one using the backup_xi.sh / restore_xi.sh scripts,
3. stay put (I don't have any pressing need to update I don't think).

Cheers,
Chris.

PS. Is there an easy way to list any additions I've made to the nagios setup on my existing machine?

You should be able to run the upgrade script without losing any of your data, though it is always recommended to make a backup first. You have other options that way too, you could create a new VM with a base "minimal" centos install, then install the latest XI version there, and then restore your backup. Any options you listed above should work well, but always make a backup!

Well with great trepidation I approached the upgrade process this afternoon.

Centos upgraded nice and easy.

I downloaded and followed the instructions and Nagios also upgraded nice and easy. It seemed to take an awfully long time, but when it finished it said there were no problems and it seems to be working ok.

Cheers,
Chris.
