Nagios2 to Nagios4 in a new machine

Dear Experts,

I just created a VM to move nagios2 to a new machine. I want to upgrade to Nagios4 once is completed.

Any thing I need to keep in mind to make it a success of an upgrade. Helpful steps...

I am new to Nagios.

Thank you!

Just create a clone, isolate it from the network and try the upgrade, if it doen't work OK, just delete it and start again.

Personally i would do a fresh install of Nagios 4 on a VM, and then import the controls from the old machine.

If it was just a version jump it would be worth upgrading, but 2 versions, probably better off with a new installation, so you don't carry over old baggage.

Thanks so much for the advice.

I am going to start from scratch this Icinga. Trying to get my boss on board. I m kind of bored with Nagios.

No problem,

Glad to help, and good look with your project, icinga looks nice, there are lots of projects based on nagios core, some of which are a lot better than nagios.
