Usually, you first have to import the root certificate,
afterwards you can 
load client certs.

The problem is that you also need the secret key for it, not
just the cert.
And PKCS#12 (.p12, .pfx) is the usual transfer format for
certificate+secret 
key packages.

You can extract the certificate from a backup, and encode it
in .der format 
with the openssl tool on the commandline:

openssl pkcs12 -clcerts -in backup.p12 -nodes -out cert.pem
openssl x509 -in cert.pem -out cert.der -outform der
