Nagios Support Forum

Hello, I want to update to the latest version of nagios XI and it tells me that my rhel 6.10 server is no longer supported and that I should install it on a more modern rhel. Is there a manual or step-by-step help on how to "move" my nagios to another server? without losing all the information?

Reading a little the backup & restore manual https://assets.nagios.com/downloads/nag ... ios-XI.pdf
I have followed the steps, worrying that my original version (5.7.5) is the same as the new version installed, but when trying to restore the tar.gz it tells me the following:

This script restores your XI system using a previously made Nagios XI backup file.

To complete the information, I have RHEL 6.10 with nagios 5.7.5 and to update it to 5.8 I need rhel 7 onwards.
I have created a new server with RHEL 8.3 and installed the version 5.7.5 of nagios xi without problems, it is working ok. But when restoring the backup I have the problem indicated above

The process is this:

Spin up new EL7/EL8 system (I would choose EL7 for 3rd party plugin/utility compatibility at this point in time)

Install the exact version of XI on the new one that the old one has:

Backup the old, transfer to the new one, restore to it:

Follow the After the Restore section of the backup/restore guide completely

Run the restore_repair script from the backup/restore guide on the new one because you are changing OS versions

Shutdown or re-IP the old:

Re-IP the new one with the old (this prevents you from having to touch firewall rules/agent allowed from directives on the devices you're monitoring:

Additionally, please see here:

Then you can upgrade your new server to XI 5.8.

If you have any issues, send us the entire install.log or upgrade.log or any errors you are seeing.

Thanks, with what you indicated .. I have reviewed well what I was doing and I was making a very silly mistake

/usr/local/nagiosxi/scripts/restore_xi.sh </full/path/to/backupfile.tar.gz

I have deleted the < character and everything works
