Convert from logins from SQL to Windows authentication

My company is converting from Novell to Windows (Active Directory)
environment. One of the SQL 200 server has more than 550 logins/users and
they are using SQL authentication.
What is the quickest way to convert all of them to Windows authentication
and keeping them to have same permission to databases & database roles (e.g
script etc). Manually recreate them is a big task.
Regards,
JohnnyAnyone can give me some advices please ?

the new login, then
drop the old login. Check out sp_change_users_logins for re-mapping users.

cannot remap the database users to the new windows logins.
e.g sp_change_users_login update_one,'user1','domain\users1'
But if I drop the database user before adding the user to the windows login,
the user will lose all the roles and permissions. Even the scripting is not
very useful because it isn't grouped by users.
Help please.
