How do I implement a test server for upgrade purpose?

[eycklin]

Hi,

We have a NagiosXI production server with valid license.

And I see the Nagios XI license allows for 3 installations, production/test/backup as following article.
https://support.nagios.com/kb/article.php?id=145

Now, the NagiosXI production server is over loading, so we need to do an upgrade.
We want to setup a new test server for upgrade purpose concurrently,
and want to restore data/settings from production server.
(and after all tests, change test server to production server ip.)

Could you provide some procedures/steps/notices for us to doing so?
(I'm a little confused on license on test server.)

Thanks,
Eyck Lin

Yes, that is true. You could have a test and backup instance in addition to your production instance.

There are many ways to create a duplicate of a machine, and the best way will likely depend on your architecture and what software you have available. If you are using a virtual machine, you may also be able to simply copy it using whatever tools your hypervisor has available.

Luckily, Nagios XI makes it easy to restore an instance from a backup, just make sure that the version of the backup aligns with that of the server being restored. You could hypothetically backup your production instance > spin up a new server > install Nagios XI on it > then restore the new instance from the backup you created earlier.

You may also want to disable notifications for the test environment, and update the IP address if the one on that machine is static.

Please refer to the following document for more detailed instructions on backing up and restoring Nagios XI.
