Mirth Connect Migration and Upgrade Services
A Mirth Connect upgrade or migration touches every interface your organization depends on, so it must be planned carefully and executed without disrupting clinical operations. Taction Software handles Mirth version upgrades and migrations from engines like Cloverleaf or Corepoint into Mirth, using channel inventories, dependency mapping, parallel running and tested rollback plans. Recent licensing changes have made many organizations revisit their Mirth strategy, and we help you decide factually. Plan your Mirth migration with experienced engineers who have done it before.
Why Organizations Upgrade or Migrate Mirth Connect
Organizations start Mirth Connect migration projects for different reasons: outdated versions without security updates, infrastructure changes, licensing decisions or consolidation from other engines. Each trigger shapes scope, risk and timing. Understanding why you are migrating helps define success criteria and avoid unnecessary changes during the project. Our Mirth Connect consulting team starts every engagement by clarifying goals, constraints and the interfaces that cannot tolerate any downtime at all. Common triggers are explained below.
Outdated Versions and Security
Older Mirth versions may lack security fixes, modern TLS support or compatibility with current Java runtimes. Running unsupported versions increases risk and makes future upgrades harder the longer they are delayed.
Licensing Changes
NextGen moved newer Mirth Connect releases to a commercial licence in 2025. Organizations must decide whether to license newer versions, remain on older ones with managed risk, or evaluate alternatives.
Infrastructure Modernization
Moving from physical servers to virtual machines, containers or cloud platforms often triggers upgrades. Infrastructure changes are a good opportunity to improve high availability, monitoring and backup processes together. Plan both together.
Consolidating From Other Engines
Some organizations migrate from Cloverleaf, Corepoint or legacy engines into Mirth to reduce licensing costs, simplify operations or standardize skills across teams responsible for interfaces. Savings must be weighed against migration effort.
Performance and Stability Problems
Slow processing, growing queues or frequent crashes may indicate outdated versions, poor database choices or inefficient channels. Upgrades combined with refactoring often resolve these long-running operational issues. Root causes are diagnosed first.
Upgrading Between Mirth Connect Versions
A Mirth version upgrade looks simple in documentation, but real environments contain custom code, extensions, database dependencies and years of undocumented changes. Upgrades that skip preparation often break channels in subtle ways that only appear under production traffic. We follow a structured process that inventories everything, tests compatibility and validates results before cutover, so your interfaces keep running reliably after the upgrade, not just immediately after deployment. Each step is outlined here.
Channel Inventory and Dependency Mapping
We document every channel, code template, global script, extension, database connection and external dependency. This inventory reveals hidden risks and defines exactly what must be tested before cutover. Nothing gets overlooked.
JavaScript Compatibility Testing
Mirth upgrades can change the JavaScript engine and underlying Java libraries. We test transformer code against the target version, fixing deprecated functions and behavior changes before production cutover. Results are documented.
Database Migration
Many older installations run on the default embedded database, which is unsuitable for production. Upgrades are a good time to move to PostgreSQL, SQL Server or another supported production database.
Java Runtime and Infrastructure
Newer Mirth versions require newer Java runtimes and may change memory and configuration needs. We size infrastructure, update runtimes and tune settings for your real message volumes. Capacity is validated under load.
Frequently Asked Questions
How long does a Mirth Connect upgrade take?
A straightforward Mirth version upgrade with limited custom code often takes four to eight weeks, including inventory, testing and cutover. Environments with many channels, extensions, database changes or infrastructure moves take longer. Migrations from other engines typically take several months, depending on interface count and complexity.
Will upgrading Mirth Connect break our channels?
It can, if upgrades skip testing. Changes to JavaScript engines, Java libraries and deprecated functions may affect transformer code. A structured process with channel inventory, compatibility testing and output comparison against current production behavior identifies issues before cutover, keeping interfaces reliable after the upgrade.
Should we upgrade Mirth or stay on an older version?
Staying on older versions avoids licensing costs but increases security, compatibility and support risks over time. Upgrading provides fixes and support but may require commercial licensing. Evaluate risk, cost and roadmap factually, including alternatives, and document the decision so leadership understands the trade-offs involved.
Can we migrate from Cloverleaf or Corepoint to Mirth?
Yes. Migration requires rebuilding interface logic as Mirth channels, recreating connectivity and acknowledgements, and comparing outputs between engines using real message samples. Phased cutover with parallel running reduces risk. Most projects take several months, depending on the number and complexity of interfaces being moved.
What database should Mirth Connect use in production?
Production Mirth environments should use a supported external database, such as PostgreSQL, SQL Server, MySQL or Oracle, rather than the default embedded database. External databases provide better performance, reliability, backups and high availability options. Upgrades are an ideal time to complete this database migration safely.
How do you avoid downtime during a Mirth migration?
Use parallel running, automated output comparison, phased cutovers during low-volume periods and tested rollback plans. Coordinate with downstream system owners before each cutover and monitor closely afterward. With proper planning, most interfaces can move with minimal disruption and no loss of clinical messages.
