LAN Crypt Migration from 3.51 to 3.9

I have an existing LAN crypt administration server version 3.51 and I have installed a new LANCrypt administration server version 3.9. Then I would like to migrate the key from the LAN crypt administration server version 3.51 to the server of LAN crypt administration server version 3.9.

However, when I followed the vb example script to dump all key from version 3.51, the GUID cannot be exported. Therefore, When I import to the version 3.9 server, the GUID is assigned a new GUID and therefore, the files encryped by the private key of version 3.51 canno tbe decrypted.

Coulf yo let met know how can I export the private encryption key with GUID from version 3.51 and then mport to veriosn 3.9 ?

Thanks !!
