Migrate/Transfer SQL Server 2008/2005/2000/7 Logins to SQL Server 2008

To my knowledge, Microsoft has not yet updated their Knowledge Base to inform administrators how to migrate SQL Server logins to SQL Server 2008. The good news is that the SQL Server 2005 login migration knowledge base article applies to SQL Server 2008 as well. Below I've included a compilation of all of the migration procedures between various versions of SQL Server.

Migration is very easy -- basically, a stored procedure named sp_help_revlogin is created and executed on the source server. The resulting output is then copied and executed on the destination server.

Detailed instructions can be found at Microsoft KB Article 918992 and Microsoft KB Article 246133. Oh, also, Dell has a marvelous 54-page SQL Server 2000 to 2008 Migration Guide. It actually outlines, in an easy-to-read style, a lot of the best practices I learned about while studying for my MCITP certification.

    Great code.
    It seems to work on migrating from SQL 2005 to SQL 2008. Still testing more in-depth.
    2 SP’s – was wondering if there was an order to run?
