Fixed-Scope Apache Tomcat to Spring Boot Migration
You need to migrate Apache Tomcat to Spring Boot. We refactor legacy WAR-based applications into modern, self-contained Spring Boot JARs with embedded web runtimes. Senior engineers, fixed scope, your timeline.
The lowest-cost way off Apache Tomcat: our migration tooling automates the repetitive work —you pay senior engineers for judgment, not keystrokes.
How we support Apache Tomcat → Spring Boot after migration
- ✓WARs refactored into standalone Spring Boot JARs.
- ✓Legacy servlets replaced with embedded runtimes.
- ✓Split monolithic apps into scalable microservices.
- ✓No big-bang cutover: migrate on your timeline.
- ✓Modern CI/CD integration built into the new code.
- ✓All work by senior platform engineers, fixed scope.
Frozen by Monolithic Code
Inability to leverage modern REST frameworks or cloud-native tooling because your Tomcat architecture doesn't integrate cleanly.
Deprecated Dependencies
Tied to old Java EE dependencies—EJBs, JAX-RPC, custom servlet lifecycle listeners—that block refactoring and slow feature releases.
Proprietary Framework Lock-In
Large, WAR-based apps built on obsolete frameworks like Struts 1 or early Spring 2.x, making microservice decomposition feel impossible.
Apache Tomcat → Spring Boot migration — your questions answered
Do I have to migrate my whole Tomcat app at once?+
Not exactly. We modernize code block-by-block. While your legacy Tomcat environment stays under vendor support (if you have a current contract), we refactor pieces into Spring Boot JARs. No forced big-bang cutover.
Can you handle deprecated Java EE dependencies like EJBs?+
Yes — that's a core part of what we do. Our senior engineers untangle old EJBs, JAX-RPC services, custom servlet lifecycle listeners, and proprietary frameworks like Struts 1 or early Spring 2.x. We wrap or replace them to fit a modern Spring Boot runtime.
What happens to my legacy support during migration?+
If your vendor contract is active, your legacy platform stays under vendor support. If it lapses, our independent third-party support covers most operational issues on the original environment while you finish the move. It is not vendor support and does not include vendor patches.
How long and how much does an Apache Tomcat to Spring Boot migration take?+
Typical projects run 4-8 months with 3-5 senior consultants. Budget ranges from $75,000 to $500,000 depending on codebase complexity and number of applications. We quote a fixed scope so you know the cost upfront.
Move to Spring Boot Without the Big Bang
Your legacy Apache Tomcat environments don't disappear overnight. That's why we support the old platform while we modernize — block-by-block. Post-migration, keep your Spring Boot apps running smoothly with our Application Modernization Lifecycle Support. 24/7 US-based engineers, 40-70% savings on support costs, and a clear path forward.
