You would need to use something like CB Juice to import new users in your CB/Joomla User management areas.

More info on CB Juice here:

With CB Juice you can also import CB field data (fields need to be created first in CB Field Manager).

Once users exist then you can use the Import functionality to assign intial subscriptions to your users.
