I have already written a small script to fix orphan
users while moving database from one server to another
server but the major problem is, that script just auto fix the login but can’t
have login with the same password which old instance/server was having.
Microsoft has provided one small script to help you out
in this situation. Look at the below script which will generate T-SQL for all
users available in current instance with password so that you can run that same
Login script in another server/instance of SQL Server and have same
login/password.

This script is copied from here.
Now all you need to do is, run stored procedure “sp_help_revlogin” with following command.
USE master
GO
EXEC
sp_help_revlogin
GO
This is really very helpful script which I have even used so
many times. Keep it handy, you never know when you will need it.
