capsman and certificate

Hi
I use capsman in my network. I have set in my capsman CAPs Manager ‘Require Peer Certificate’ and CA Certificate set to my certificate (no auto).
Now how i can add new device to capsman manager without turning off this options? If i disable this options : CA Certificate set auto and no check Require Peer Certificate then all my devices lose connection for one moment.
How manualy control certifications, i try impor CA certificate to my new device but this not work .
