login script to move an instance of sql 2008 R2 to another

Hi,

I need to know what are the steps to capture logins when we move an instance from one server to another. I know the sp_helplogins but the issue is the login can be created in the destination server, but both the windows and sql logins doesn't have rights. Is there any way to remap that.

In sql 2005 sp_change_users_login used to remap, but this doesn't work in sql 2008 R2

Thanks
