My understanding is that InDesign CS6 will not open inDesign CC files unless they're saved as InDesign Markup (IDML).



Tried opening a CC document in CS6:



So yes, IDML ...

Or change your workflow to include saving an archive version of all your CC projects to an earlier version. Of course, that might get rid of whatever CC-specific stuff you may have used in the document, which kind of makes using the CC version moot in the first place ...

I can't see where this won't become a huge issue for Adobe -- at some point I wager they'll have to come up with a solution for opening/saving documents orphaned by an expired subscription ...
