Moving settings from one computer to another

Dear all,

I wouid like to transfer my calibre configuration (e.g. email settings to share books by email) from my old computer to my new computer (running Linux).

I have access to my old disk, and I can see the /opt/calibre folder. I have copied that folder to /opt in the new machine, but calibre doesn't have pre-filled settings.

Is it possible to do this?

Cheers and thanks, Manuel
