Import Local CA from 5.x to 6.2

Hello,

we have setup a new machine with the supplied image and want to transfer all certificates AND the root CA inlcuding the certificates. I cannot find any information how to transfer the Local CA certificates from the old 5.x version to the new 6.2 version. In the documentation i cannot find any information on how to create a root CA from existing certificates. From the GUI i can only create a new Root-CA with new cerficiate which is not workable for us because our communication partners already have our old root certificate.

Best Regards,

Vincent
