Mirth Connect Migration Services
Moving off a commercial integration engine is usually driven by one of three pressures: a licensing renewal you don't want to sign, staffing costs for a scarce scripting language, or a modernization push toward cloud and FHIR. Whatever the trigger, the risk is the same — your interfaces carry live clinical and financial data, and a sloppy cutover shows up as missing results or dropped charges.
We migrate organizations onto Mirth Connect from every major engine, with a methodology built around proving equivalence before anyone flips the switch. Over 12+ years and 5,000+ interfaces, the migrations that go wrong are the ones that skip the parallel-run period — so we don't skip it.

Engines we migrate from
Iguana → Mirth
Lua transformer logic rewritten in JavaScript/Groovy. Typical mid-size timeline 3–5 months.
Rhapsody → Mirth
Route logic mapped to channels; JS-to-JS translation runs faster. 3–6 months.
Corepoint → Mirth
Action-library configuration rebuilt as scripted transformers. 3–6 months.
Cloverleaf → Mirth
Tcl rewritten; the most common migration we see in 2026. 6–12 months end to end.
Ensemble / InterSystems IRIS → Mirth
ObjectScript migration is the heavy lift. 4–9 months.

Our migration methodology
Discovery and inventory
Every channel, connector, transformer, and downstream system documented, with risk flagged.
Fixed Statement of Work
Scope, deliverables, and price agreed before kickoff. No timesheet billing.
Channel rebuild in Mirth
Interfaces re-implemented in your own Git repo, which your organization owns from the first commit.
Parity testing
Channel-by-channel, message-by-message comparison against the source engine to prove equivalent output.
Parallel run
Both engines run side by side under real traffic until the new environment is proven. This is the step that builds confidence and prevents surprises.
Zero-downtime cutover
Interface-by-interface, not big-bang, so clinical workflows never stop.
Post-cutover support
Monitoring and stabilization, with an option to roll into managed support.
Cost and timeline
Engine migration sprints start at $34,500 for a defined scope, with larger multi-channel estates scoped individually. Timelines run from about 3 months for a mid-size JavaScript-engine migration to 6–12 months for a large Cloverleaf estate. Three or more sprints purchased together qualify for a multi-sprint discount and can convert into ongoing Silver support. See all fixed-price sprints and the unified pricing page.
Migration is one part of our broader Mirth Connect support practice — most clients roll from cutover into a monthly managed tier so the new environment stays healthy.
