Laravel Shift is a paid service that can upgrade a Laravel project. I've used it a couple of times. Although some manually work is needed to complete the upgrade, it has saved me many hours. The service has recently shifted it's 1000th project, a major milestone. In a post on his blog Jason shares how he started the service and where it's going in the future.

In this post, I want to focus more on reaching the milestone of 1,000 Laravel applications upgraded. This may not sound like many, however for my first SaaS product it marks the achievement of my stretch goal. So allow me to share the most important decision, biggest challenge, and what the future holds for Laravel Shift.
