System Migration
System migration is the process of transferring data, applications, and IT infrastructure from one computing environment to another, such as moving from on-premises servers to cloud platforms, upgrading legacy systems, or consolidating multiple systems. It involves planning, execution, and validation to ensure minimal disruption and maintain data integrity, performance, and security. This process is critical for modernizing IT infrastructure, improving scalability, and reducing operational costs.
Developers should learn system migration to handle technology upgrades, cloud adoption, and mergers/acquisitions, where moving systems efficiently is essential for business continuity. It's used when migrating legacy applications to modern platforms (e.g., moving from a monolithic to microservices architecture), transitioning to cloud services like AWS or Azure, or consolidating databases after company mergers. Mastery of this skill ensures smooth transitions, reduces downtime, and leverages new technologies effectively.
