Yes and no. You want to copy the lists/LISTNAME/config.pck file for
sure. You may or may not want to copy the others. In particular, if you
copy lists/LISTNAME/requests.pck and there are held messages for the
list, you also need to copy all the data/heldmsg-LISTNAME-* files or you
will wind up with non-existent held messages.

It will do for the list's config, but it won't move list members or any
of their settings or passwords. Moving the config.pck will move these
things assuming you aren't using some non-standard MemberAdaptor.

See the FAQ at <http://wiki.list.org/x/4030682> and the list posts
linked therefrom.
