Nagios Support Forum

Hello:
Is my license key (which was renewed) good for my one existing Nagios XI server, or can the license key be applied to a (or up to "x") new server(s) in parallel?
In other words, can I apply my existing license to a new server while the "old" server is online and not have any licensing issues?
Do we require to purchase a new license?

Thank you.

I would contact [email protected] for specifics, but basically each license is good for one main/primary installation, one backup/failover installation, and one testing/dev installation. As long as only the main install is actively doing meaningful checks you are in the clear. The backup basically kicks in if the main goes down, so it can have a copy of the same configs but should not be running unless the main is down. The testing install is for trying upgrades, new plugins, addons, etc. before doing so on the main install, and so should be used as minimally as possible.
