Four risks in a webMethods migration, and how we remove each one

‍

None of them are about whether SAP Integration Suite is the right target. They are about whether hundreds of interfaces can move without breaking what already works.

Your flow service logic is converted, not rewritten

Flow services are a proprietary graphical language, and the mapping steps sit inside them rather than as separate artefacts anyone can lift out. That is why most migrations treat every transformation as new development. Migration Studio extracts the transformation logic from your Integration Server packages and converts it with field structures and business logic preserved. Equivalence is then proven by test, not by code review.

Every interface regression tested against webMethods

We capture baselines from the running platform before anything moves. Real payloads are replayed and output compared field by field against the webMethods baseline, with interface-level pass/fail dashboards your stakeholders sign off against instead of an opinion.

Hidden complexity found before the budget is fixed

Behaviour spreads across flow services, Java services, adapter configuration and publish/subscribe routing, and an estate that has been through several major versions carries patterns nobody would design today. An inventory built from service names misses most of it, which is how migrations discover their real scope after the number is committed. A pilot spanning low to very high complexity surfaces it first.

Your team reviews results instead of producing them

Migrations stall on capacity, not intent, and hand-testing hundreds of interfaces lands on the same people keeping the current landscape running. With up to 80% of the conversion work automated, the effort your team spends moves from producing test evidence to reviewing it.

Why Rojo

Automation is what makes the difference on a migration

Two parts of a webMethods migration take most of the time: converting flow service logic that was never meant to leave the platform, and proving the result still behaves the same.

Both have to be repeated for every interface, which is what stretches a timeline. We use our own tooling for both.

Rojo Migration Studio

Our own tooling, run by our consultants against your landscape. You get the benefit without buying a tool or training your team on one.
‍
✔ Reads your Integration Server packages and flow services
✔ Extracts and analyses the mapping and transformation steps inside them
✔ Converts them for SAP Integration Suite with field structures and business logic preserved
✔ Validates converted mappings for compatibility automatically

Up to 80% of the conversion work automated.

Regression testing framework

The framework replays your real payloads and flags any mismatch in mapping, routing or payload structure during execution, not in UAT.
‍
✔ Field-level comparison against the webMethods baseline
✔ Baselines captured from the running platform before anything moves
✔ Allowed deviations handled by configuration
✔ Runs unattended across the full test set
✔ Interface-level pass/fail dashboards for sign-off

Weeks to days on validation cycles, with up to 70% less manual regression effort

And we won't migrate your technical debt

Every interface gets one of five decisions in the assessment, before any migration work starts. We work through the estate interface by interface, rate each one for complexity, and agree the split with your team rather than handing it to you. On a decade-old landscape, retire and replace are usually bigger categories than anyone expects, which means the project is often smaller than the interface count suggests.

01
Migrate as is

Works, still needed, no redesign case. The category automation handles best.

02
Modernise

Worth keeping, but the pattern is dated. Nightly batch becomes real time, point-to-point becomes event-driven.

03
Migrate and redesign

Needed, but the current design doesn't belong on the target platform. Long-running flows and Broker-era publish/subscribe designs land here.

04
Replace with standard content

A prebuilt adapter already covers it. No reason to migrate custom code.

05
Retire

Every interface retired is one you never pay to migrate, test or run again.
