Introduction to Continuous Integration for Legacy Systems

Continuous Integration (CI) is a development practice where developers integrate code into a shared repository frequently, preferably several times a day. This chapter will provide a detailed explanation of how to implement CI in legacy systems.

Understanding Legacy Systems

Legacy systems are old methods, technologies, computer systems, or application programs that continue to be used, typically because the user (typically a business) does not want to replace or redesign them. Integrating CI into these systems can be challenging but is crucial for efficient software development and deployment.

Benefits of Continuous Integration for Legacy Systems

Implementing CI in legacy systems can lead to several benefits such as improved code quality, reduced risk, faster iteration, and increased confidence in software releases. It also allows for faster detection and resolution of bugs, leading to more stable software.

Challenges in Implementing Continuous Integration for Legacy Systems

Legacy systems often lack automated testing and deployment processes, making the implementation of CI challenging. Additionally, these systems often have complex dependencies and may not be designed for frequent updates and deployments.

Steps to Implement Continuous Integration in Legacy Systems

The first step is to understand the existing system and its dependencies. Next, automated tests should be written to ensure that changes do not break existing functionality. Then, a CI server can be set up to automatically build and test the system whenever changes are made. Finally, the team should be trained on the new processes and tools.
