asselstine / How to migrate super old Rails databases
Created August 18, 2016 23:21
When you have a bunch of poorly written Rails migrations that include data migrations, sometimes it is impossible to update very old databases because the migrations required old versions of the code.
How to get around this?
Use git-bisect.
