Can I downgrade SSIS packages to run on older version of SQL We have some new SQL 2008 SSIS jobs that were recently developed, mostly to do some simple flat-file loading and targeting a set of tables on a 2008 server.

As it turns out, they may have to run on a SQL 2005 server for both the SSIS and target tables.

Is it possible to downgrade the packages somehow, instead of redeveloping them from scratch?

Obviously any 2008 specific SSIS features would disappear; but it would be nice to not start with a blank designer screen.
SSIS Downgrade should do exactly what you need.
