Change NPM Integration (Validation )IP address

Hello,

We have a scenario where our NPM and NCM are on different Windows servers.

Now during initial NCM installation, it asks for NPM server IP for validation.Once you provide it, it uses uses that IP to integrate/communicate with NPM server.

Now I want to change that NPM IP which NCM uses for integration, Is there a way to do it?

I access my servers remotely, we have two NIC once for remote desktop and one for Polling. So how do I make change? Is there risk involved loosing connectivity?

Please suggest, Thank you
