The challenge
The monolith's deployment process required a full regression cycle for even small changes, and the team had no realistic path to modernize without risking an outage.
The approach
Introduced a strangler-fig migration plan: new functionality was built as Spring Boot services alongside the monolith, with traffic shifted incrementally as each piece was validated.
The outcome
The team shipped independent services on a weekly cadence within the first migration phase, without a single regression cycle blocking a release.
