share between numbers 3.2.2 and 3.5
I have a MacBook Pro at work that I have to keep on Mavericks and a Mac Pro at home running Yosemite. I need to be able to share Numbers documents between the two. Numbers 3.2.2 saves the documents to the old iCloud Documents & Data, but the new one does not appear to have a way to see those documents. It appears that there is no way to share between the two minor versions of Numbers (iWorks for that matter). I can share those documents between Mavericks and iOS 8.
Does anyone know how to get Numbers 3.5 to access documents in the old iCloud?
If this does not work, I am guessing that using DropBox is my best option - thoughts?
Mac Pro, OS X Yosemite (10.10.1)
