Migrating from a modular monolith to microservices offers several benefits, including scalability, independent deployability, and team autonomy. However, the transition requires thorough preparation, particularly around module boundaries, data encapsulation, and communication patterns. Begin by selecting a self-contained module to extract, update inter-service communication methods, and consider implementing an API Gateway to manage clients. Lastly, adopt a data migration strategy that suits your system's complexity and disruption tolerance.
