Help > Updates Doesn't upgrade major version to 2014, only applies minor version updates

I have Adobe Creative Cloud for OS X deployed to many machines using CCP and Casper and I have now set up AUSST.

On one test machine, I opened one CC application and went to Help > Updates and installed all available updates. It appears to only install minor version number updates, not Major version number upgrades, so my machine is not on CC 2014.

Is this expected behaviour? Should I now be on 2014, or do I need to build a new package using CCP for 2014?

If I need to build a new package, what do I do regarding the existing installations? DO i need to remove all those components first?

Thanks,

Alan.
