Is there any sort of automated or semi-automated upgrade path from SSIS packages built using the 1.2 Attunity Connectors to the 2.0 Attunity Connectors that does not require rebuilding every single Oracle Datasource object?

We have a very large (500 table) data warehouse ETL package that utilizes the 1.2 connectors as our Dev environment is SQL Server 2008. Unbeknownst to us, our production environment was upgraded to SQL Server 2012 - and while we don't have a problem with this per se, it's the sheer amount of work required to upgrade the packages to work under the new SQL environment that is currently holding back our deployment.
