FreeRADIUS only uses the certs/keys that are given in the
configuration. So look in mods-enabled/eap (or other similar locations)
and see what files are being included. If they're still in the normal
place then they'll be in the certs/ dir.

Likelihood is it's just a certificate file (possibly with the full
chain), a key file, and a ca root cert file.

"freeradius -XC | grep pem" will probably list everything.

Just copy those over.

Back up the config before you start so you can roll back if needs be
and you can't really go wrong.
