You can subscribe the members of the larger list to the smaller list:

First export the subscribers using the "list_members" command from the
server command line:

/usr/lib/mailman/bin/list_members  your-list-name  >

Then import those addresses into the smaller list. I believe there are
two ways to do this:

--You can use the "mass subscribe" feature of the smaller list to import
the addresses. Paste the exported addresses into the "mass subscribe"
page on the admin web interface. Any duplicates will be ignored. This
method allows you the option of sending invitations rather than
arbitrarily subscribing them (based on your current setting in the admin
interface). If you send invitations, your invitees get the option of
choosing between regular and digest subscriptions.

--You could also use the "add_members" command from the server command
line. I believe this arbitrarily subscribes them without the option of

/usr/lib/mailman/bin/add_members  -r filename-for-member-list your-list-name

The -r subscribes them as regular members -d as digest members.

Hope that helps.
