Export and Import a Server (or at least a map)

1
Hello everyone,

I have a question:
Has anyone ever "copied" a life is feudal server to a local server?

I've tried that a few times and the server was running, but I was never able to join because there was always an error message something with CR_Error code...

Or at least copying the map of a running server to a local server...

I exported the database and imported it to the local server and then copied the server files accordingly. As I said, the server was running, but I couldn't join.

Is there a trick or something that you should definitely pay attention to, because otherwise it won't work?
I am grateful for any help!

Best Regards
Drago
