How we support IBM WebSphere Application Server → Spring Boot after migration

✓Fixed-scope projects – no cost overruns.
✓Senior platform engineers lead every migration.
✓Vendor support stays active during the move.
✓Third-party support covers most issues if your renewal lapses.
✓Save 40–70% on legacy support while you plan.
✓24/7 US-based support – day or night.

Thick-client EJBs and legacy SOAP web services

Your codebase is tangled with heavy EJBs and SOAP dependencies that don't fit modern cloud environments. Refactoring without deep WebSphere expertise is risky.

Stateful session beans relying on WebSphere clustering

Stateful beans that depend on WebSphere's memory replication are hard to migrate. We systematically convert them to stateless, idempotent designs for Spring Boot.

Direct dependency on IBM-specific resource adapters

Tight coupling to proprietary adapters blocks your move. Our engineers replace each adapter with standard Spring Boot connectors, preserving business logic.

IBM WebSphere Application Server → Spring Boot migration — your questions answered

How do you handle stateful session beans from WebSphere?+

We analyze the session bean usage and refactor the state into external stores (e.g., Redis, database) so the Spring Boot services are stateless and can scale horizontally.

What happens to my IBM-specific resource adapters?+

We map each adapter to a standard Spring Boot equivalent (JPA, JMS, etc.) and test the integration. The legacy adapters remain in production under vendor support until the new code is validated.

Can we migrate incrementally, or is it all or nothing?+

Incremental extraction is standard. We convert one module at a time using a strangler fig pattern. Your WebSphere environment stays live under vendor support throughout.

What if our vendor renewal lapses before the migration finishes?+

Our third-party support covers most operational issues on the legacy platform while you complete the move. It is not vendor support and does not include vendor patches, but keeps you running.

Post-Migration: Managed Spring Cloud Runtime & CI/CD Pipelines

Once your WebSphere monolith is fully converted to Spring Boot microservices, keep the momentum with our managed Spring Cloud support and continuous deployment pipelines. Your team stays focused on features, not infrastructure. Start with a Monolith-to-Microservices Assessment. Request yours today.
