It gives out clues for things that are not upgraded and needs addressing and most of the things needed to be automatically upgraded are handled and placed as a git commit message. Review collected by and hosted on G2.com.

The only thing I dislike is that Laravel Shift has to access the repository directly and this could be an issue on some client who wants no one else accesses their codebase. Another is that, you can't upgrade from one version and skips several versions. You need to upgrade incrementally from one version to another which might take time but I guess it's what makes your upgrade stable. Review collected by and hosted on G2.com.
