changing the Jamf build in certificate - what is to be considered ?


Hello community,
we have to change the build in Jamf certificate to one, issued by our own certificate server. Right now, we have enrolled about 10 to 15 Mac clients.
The clients were all enrolled by the users itself.
I think, if we are changing the Jamf certificate, we have to update installed certificate (which was installed at the enroll process)at the clients, too ?
Is there a "best practice" how to do changing the servers certificate and the certificate installed on the enrolled clients ?
Do I have to enroll the clients again or is it enough, to enroll the new Jamf certificate ?
Thank you for your answers,
