1. It is best not to move the certificate casually
2. The push server you built yourself needs to push the P12 certificate derived from the certificate. The server needs the password of this P12 certificate. The passwords on both sides must be consistent before they can be pushed.

Two development/release certificates (cer files) can only be created through two CSR files, that is to say, they can only be installed on two computers for use. There is no way for the third computer to obtain development qualifications by installing the certificate. The third computer needs to export the private key (.p12 file) corresponding to the cer certificate from the first two computers , and a password needs to be set. The subsequent operations are the same, which is to install the cer or p12 file, and then install the pp (Provisioning Profiles) file. In this way, one certificate can be used to develop applications on multiple computers.
