Legacy System Integration
Legacy system integration connects older applications, which often have no API or documentation, with new systems. The approach can be an API layer on top of the database, scheduled file exchange or middleware, so the legacy system keeps running while it is modernized in stages.
Legacy Modernization
Business problems
Data can only be taken from application screens or manual exports.
Replacing a core system at once threatens daily operations.
The original developers are gone and documentation is minimal.
What we build
Expose legacy data through a secure, limited API.
Scheduled data export and import with validation and logs.
Translate legacy formats and protocols into modern ones.
Functions move to the new system in stages until the legacy system can be retired.
Example applications
Legacy data is shown in a web portal without replacing the application.
A mobile app uses an API built on top of the legacy database.
Legacy data becomes a source for AI applications through an integration layer.
Architecture & approach
Study the database, data flows and dependencies of the legacy system.
API layer, file exchange or middleware depending on conditions.
Integration is tested side by side without disrupting operations.
High-value functions move first.
Technology & integration
Deployment
| Option | Description | Best for |
|---|---|---|
| On-premise | The integration layer runs on the same server or network as the legacy system. |
|
| Hybrid | A local agent forwards legacy data to cloud services. |
