NAC appliance: SSL certs renewal

[vladimir.agafin]

Hello!

I have the following question:

SSL certificates are going to expire soon on my NAC Mgr, Srv and NGS. So after I'll generate new CSRs will the existing certficates still be valid and used?

All systems are in production, and I don't have any testing enviroment to check, may be someone has done it already.

If you use the same CSR that you generated for the original cert, then you just import the new cert and it will be replaced. I didn't try to generate a new cert as I wasn't sure if it would overwrite the old private key.
