NCPA Agent behaviour post upgrading Nagios

hi team,
we are on version nagios 5.6 and would like to upgrade to 5.7. As per the documentation NCPA will be the default agent instead of nsclient/nrpe so what will happen to the machine which has NSclient/NRPE already installed on them.
Do we need to uninstall the nsclient/nrpe agents from all the hosts and replace it with the NCPA agent?
Do we need to create service checks again after installing the NCPA on those machine?

Hi
@IT-OPS-SYS,

Thankfully, that's not a requirement to upgrade to 5.7. We are just moving all of our development efforts into improving the NCPA agent and adding new functionality in 2021 and beyond. And we'll continue to provide bug fixes and security updates for NRPE.
NSClient is a 3rd party agent, and there's a configuration wizard available in 5.7 for any systems running this agent.
Do we need to create service checks again after installing the NCPA on those machines?
If you do plan to install NCPA on your remote systems, it will be necessary to set up new checks using the NCPA Wizard or the Core Configuration Manager.
Hope that helps. Let us know if you have further questions.

suppose we have nsclient/nrpe installed on the windows host and we would like to replace it with the NCPA agent then in that case after installing the ncpa client do we need to create new service checks as well.
can we have both nagios agents installed on the host at the same time?

Yeah, it's necessary to set up new checks setup since it uses different plugins/arguments. After installing, you can use the NCPA configuration wizard to set this up.
See:
How To Monitor Devices Using The NCPA Agent and Wizard
You can have both agents installed at the same time.
