Migration of Legacy Systems Should Be Continuous
Why is migration planning still using a waterfall methodology? Companies need flexibility even when modernizing and they need to learn during each step in the process.



Development teams see the benefits of continuous processes. Most companies now use Continuous integration (CI) and continuous delivery (CD) in support of DevOps. It is considered common or at least the goal of modern development. But modernization projects still talk about multiple year time frames with different phases where each system will be deployed. This is a waterfall approach.
