What is the best way to update my old "agents" nrpe to ncpa.
I have about 300 servers configured with nrpe and others with nsclient ++
My question is how to update without losing the historical information in nagios.

Hi @supportcl,

If you switch from NRPE to NCPA, the performance data will be generated using different plugins so the new data coming in will be on a different graph even if it's for the same type of check (e.g. CPU load).

The graphs from the NRPE checks will not be deleted but the host or services will not be UP and would not be generating new data. You can continue to keep those in your configurations, but you'd want to disable notifications.

Also, Nagios XI does have an Agent Deployment feature for NCPA, that can help install this automatically on the remote systems interface.

Automatic Agent Deployment

Hope that helps answer your question let us know if you need clarification on anything.
