Migrate MuleSoft to Spring Boot — in your own environment

Escape the MuleSoft Lock-In.

Convert your Mule 4 apps to production-ready Spring Boot — and prove every response field matches the original — all inside your own environment. Your source code never leaves it: no upload, no third-party LLM, no sub-processor.

Built for engineering and integration leaders modernizing large Mule 4 estates — without a risky, multi-year rewrite.

The MuleSoft Trap Is Real

Your MuleSoft contract renews every year. The cost grows. Your API estate grows. And the quote for getting off MuleSoft keeps coming back: years, millions, and risk you can't quantify. Meanwhile, you're paying for a proprietary runtime that requires specialist talent, resists cloud-native deployment, and keeps your architecture roadmap in someone else's hands.

The Cost

Six or seven figures a year in licensing, growing every renewal — with zero architectural freedom included.

The Migration Barrier

Hundreds of developer hours per application. A large estate runs to years and millions in manual effort. That's why nothing gets migrated.

The Validation Risk

After manual migration, how do you prove it works the same? Without automated testing, you run parallel environments for months.

Deploy. Convert. Prove. Report.

1

Deploy

Run API Modernizer inside your own environment — on-premise, in your VPC, or fully air-gapped. Your code never leaves it.

2

Convert

API Modernizer parses your flows, translates DataWeave, and generates Spring Boot code for all 26+ enterprise connectors — in minutes.

3

Validate

Your existing Postman tests run against both systems. Field-by-field comparison. MATCH/MISMATCH per endpoint. Proof before you decommission.

4

Report

Board-ready PDF: ROI, 5-year TCO, performance benchmark, executive summary. Generated automatically.

Idiomatic output

From Mule XML to Spring Boot you own

Flows and connectors become idiomatic Spring Boot — @RestControllers, JdbcTemplate, WebClient — yours outright. Your DataWeave keeps working too: it runs on the embedded Transmute engine as editable scripts your team already understands, with no rewrite.

Mule (XML)
<db:select config-ref="db">
  <db:sql>SELECT id, name FROM customers</db:sql>
</db:select>
Spring Boot (Java)
jdbcTemplate.queryForList(
    "SELECT id, name FROM customers");

100%

Functional match on deterministic endpoints

Every response is replayed against a live Mule runtime and scored field-by-field — proof before you decommission anything.

Enterprise connectors, converted automatically

Database, HTTP, Kafka, Salesforce, SAP, and more — each mapped to its idiomatic Spring Boot equivalent.

Cut Over Without Betting the Business

Run the converted Spring Boot app alongside your live Mule app during an observation window, comparing responses field-by-field. Shift traffic in stages. If anything looks off, revert the deploy and point traffic back to the still-running Mule app — your original stays untouched until you have signed off. Nothing is decommissioned until you decide it's proven.

Two Weeks. Your App. Your Tests. Your ROI.

Give us one Mule application and two weeks. We deliver the converted Spring Boot project, functional comparison report, and personalised ROI analysis — ready for your board. Run it in your own environment; nothing leaves your infrastructure. No long-term commitment. You keep everything.
