Thanks for sharing.

Just wanna add one note about the code for

changing the Maintenance plan ownership :

use msdb;

go

update dbo.sysssispackages

set ownersid = (

select sid from msdb.sys.syslogins where name = 'sa')

where [name] = 'MaintenancePlanNameHere';

It only works for SQL2008 because there is no dbo.sysssispackages in the MSDB in SQL2005. Use dbo.sysdtspackages90 in SQL 2005.
