What about my custom packages and dependencies?

The Composer dependency tree is usually the hardest part of a Laravel upgrade. Some third party packages have not been updated to support the target Laravel version and need replacement, patching, or temporary forking. Custom packages built in house need direct refactoring. Our upgrade audit catalogues every package, its current version, the target Laravel compatible version, and a recommended action (update, replace, patch, or remove). The dependency plan is signed off before the upgrade work starts so there are no surprises mid project.
