CAPsMan Migration certificates

Hello, I have a CAPsMan with 69 AP.

I need to make an identical but backup CAPsMan in case the first one fails.
The antennas are all with a certificate and locked with the certificate of the current CAPsMan.

I have already exported the controller configuration but for the certificates I don’t understand which ones I need to export.

Do I only need to export the certificate of the CAPsMan or also all the antennas?

Because by testing if I only put the certificate of the controller the antenna is adopted but the backup controller does not have all the certificates of the antennas with the “I” designation. Could you please help me?

Thanks in advance!
