Sorry for the long title. Is it possible to have Snow Leopard in one partition and Yosemite 10.10.2 in another and copy and paste Users docs from Snowy to Yosemite? My wife needs to try to see if Yosemite "cures" some problems she's encountering using Snowy while not damaging the footnotes on a large book she's writing. Since the footnotes are VERY extensive and would be a disaster if they were disturbed, she's afraid to just upgrade to Yosemite until she's sure that the footnotes will come through unscathed. To me, the idea of copying and pasting is equally as risky as just upgrading in the normal way, but it's not my book.
