Can you deploy a Data-tier component extracted from SQL Server 2014 CTP1 to SQL Server 2012?

This should not be possible according to documentation here  and quoted below unless the DAC Framework version are the same.

'A DAC package or export file built with one version of the DAC Framework cannot be processed by an earlier version of the DAC Framework. For example, a DAC package extracted using the SQL Server 2012 client tools cannot be deployed using the SQL Server 2008 R2 client tools.'

This post is about a little experiment to test the validity of the above statement. In an earlier post in HodentekMSSS.blogspot.com here a .dac extracted from SQL Server 2012 was deployed to CTP1:


The above post was about a DAC package extracted from SQL Server 2012 Express on Windows 7 Platform (x64) and deployed to SQL Server 2014 CTP1 on Windows 8 Preview platform.

In this post the database created using the above procedure was extracted and deployed back to SQL Server 2012 Express on the other partition. This was also successful in violation of the previously quoted procedure.

The reason was the DAC Framework versions were found to be the same on both servers using the DacUnpack utility.

The DacUnpack utility unpacks the .dac files. Here are the two files opened in Safari browser.
