Every line of code you write has ongoing costs. It needs tests, security patches, and updates. Old code can slow down your team and create risks. That is why learning to remove old code is important.
Deprecation is the practice of marking old code for removal. Migration is the process of moving users from old systems to new ones. Together they help keep your codebase healthy and lean.
This skill teaches you how to plan deprecation from the start. You will learn when to remove code and how to guide users safely. The result is less maintenance work and fewer problems down the road.
