Upgrading from Solidus 2 to Solidus 3 | Super Good Software

I recently had the pleasure of upgrading a long-running e-commerce storefront from Solidus 2.11 to Solidus 3.0. Solidus is a free and open-source e-commerce platform, silently helping thousands of stores turnover hundreds of millions in revenue each year. Like most sensible software projects, Solidus sticks to the convention of only allowing breaking changes in major version bumps, so while I knew that the jump from 2.11 to 3.0 was going to take longer than a day, I figured I’d have it wrapped in a week or so.I was super wrong.
