Frequently Asked Questions
Which Java versions do you support?
We favor supported LTS releases and choose the target based on framework compatibility, runtime support and migration constraints.
Can you upgrade older Spring applications?
Yes. We assess Java, Spring, dependency, namespace, security, test and runtime changes, then upgrade in controlled stages.
Can Spring Boot support high-volume payments?
Yes when data access, concurrency, state transitions, idempotency, messaging and resource limits are designed for the actual workload.
