Negative impact on importing https certificate! NGFW 16200

[AfterMath]

Hi there

We are running 16200 cluster ngfw, the https inspection CA certificate is about to expire. We want to import a new p12 certificate and we are facing a problem to import the new license. The old one is expired, so we want to import the new one.  We already have a certificate generated in the machine, and we want to import.

This screen is from smart dashboard.

Is this the right way to import an https certificate? 

Performing importing certificate has a negative impact for importing/change the certificate?

Yes, this is the procedure according to: https://support.checkpoint.com/results/sk/sk108641 
This won't take effect until a policy installation is done outside of SmartDashboard.
