Dave, Use this query to obtain the information you are looking for: SELECT [dts].[name] [package_name], SUSER_SNAME([dts].[ownersid]) [package_owner] FROM [msdb].[dbo].[sysdtspackages90] [dts] ORDER BY [package_name]

yes you can use same configuration file. But you have to configure each package to point to this configuration file. Check the paths of dev and live server are the same. If you are saving passwords in configuration , you have to manuaaly add the password for the .config xml file. Check that as well

best is to use package configurations. You can save all your settings in XML file and chnage those files when required.
