Jon, that's a good question. I haven't done this myself, but I would think you could do this in the console. Off the top of my head, something like:
sql_playground = Vanity::Playground.new
sql_palyground.establish_connection(redis_params)
redis_playground = Vanity::Playground.new
redis_palyground.establish_connection(redis_params)
And then maybe copy the experiments, metrics, participants and conversions from one to the other?
I might be able to play more with this tonight, but if you figure it out, please let us know!
