Nagios Support Forum

Hello,
We are currently running Nagios XI 2012R2.9 on RHEL5 and would like to upgrade to 5.3.0. We already attempted the upgrade on one of our lab servers and we ran into php 5.2/5.3 issue which has been discussed in another thread. Going forward we would like to know the best approach we should take for our remaining servers. Should we just upgrade to RHEL6 and do a fresh install? If so, how can we get our configurations over from the previous version? In addition, for the fresh install will we require outside network access? Our servers are on an isolated network.

Thanks

You should follow the procedure Backing Up And Restoring Your Nagios XI System.

All new installs should be done on clean instances of CentOS/RHEL 6 or 7. There is no supported upgrade path from 6 > 7 and this is due the OS not supporting upgrades between major releases.

For best results, especially in your case, restore your backup to a Nagios XI clean install of the same version the backup was created on. You are limited to CentOS/RHEL 6 in this case because your current version of Nagios XI doesn't work on 7.

All that being said, 5.3.1 is in the works right now because of a couple of issues a few users saw. You might wish to factor that into your upgrade plans.

We are going to install RHEL6 and re-install nagios. For a clean install is there an offline install package? What is the outlook for 5.3.1?

Offline installs are done from here: Nagios Repositories.

5.3.1 should be available in a matter of days although offline installs may be a bit more than that.
