In order to import a user certificate from another device you would have to import both the private key as well as the public cert. This is possible providing you can
get the data into the appropriate format (such as pkcs12 file) in the 1st instance.
For example see KM Doc ID 184701.1 for an example of how to do this using openssl.
Just to clear there are some issues you need to be aware of. Only certain versions of OHS wallets support wildcard or certs with subject alternate names. Also certain
specific digests as well. Also I note you don't mention what version you are running. That can matter. Generally the later the version the more options
you will have.
