Hopefully you are using Psych for everything, but if you have legacy Syck YAML files lying around you could be in for some pain because they are not necessarily compatible. In my case, I had a bunch of i18n translation files emitted with Syck which uses an incompatible escape code structure instead of plain utf-8, thereby rendering the files unreadable by both Psych and humans alike. My solution was a little script utilizing the fact that the engine can be swapped dynamically.
