Having googled it (and looked on the heroku site) - i just can't find a set for instructions for setting a new rails app's database connection to be to a basic db created for a different (earlier) app. I know there's something to do with swapping the "color" of the databases available - but i have no idea how... and links or any simple instructions massively appreciated.
ps - i gave seen this question, but it is a couple of years old, and it seems things have moved on at heroku since then.
