There is some information out there but it took a little time hunting down what I needed; thus, I’ve summarized some of the main steps to help get others up and running with Flask, Heroku and Alembic.</p> <p><strong>Why migrate?</strong> Best practice is to avoid recreating your database(s). Usually you just want to make changes to the existing database(s) and track those changes. If at any time you need to go back to a previous version, the migration docs will help you easily revert to an old version / schema and then upgrade back to the most recent depending on your needs.</p>
