If all you need is upgrade and downgrade, you can use the code from this article with your modifications and tweaks. It’s based on some simple conventions without any possibilities for configuration or customization, but again, YAGNI (you aren’t gonna need it). If you end up needing it, then you can just modify the script and get on with more interesting stuff.
