Wrap legacy databases, mainframes, and proprietary systems with secure REST APIs instantly. Enable modern applications, AI, and integrations without risky migrations or rewrites.
API-based modernization wraps legacy databases, mainframes, and proprietary systems with auto-generated REST APIs instead of rewriting or migrating them. The legacy system keeps running unchanged while DreamFactory sits in front as a modern API layer — adding JWT, OAuth, role-based access control, and rate limiting to systems that predate modern authentication.
That bridge lets modern applications, data warehouses, and AI workflows use legacy data through standard endpoints. The Vermont Department of Transportation used this approach to connect a 1970s IBM mainframe to modern Oracle databases without replacing core infrastructure.
Why DreamFactory
Instant API Wrapping
Auto‑generate REST APIs from legacy Oracle, AS/400, SQL Server, and mainframe databases.
Zero Disruption
Legacy systems keep running unchanged — DreamFactory sits in front as a modern API layer.
Modern Security
Layer JWT, OAuth, RBAC, and rate limiting on top of systems that predate modern auth standards.
Universal Connectivity
Bridge legacy data into modern apps, data warehouses, and AI workflows through standard APIs.
Self‑Hosted
Keep sensitive legacy data on‑premises while exposing controlled API endpoints to modern systems.
Auditable Access
Every API call against legacy systems is logged with user identity, request, and response metadata.
No. The legacy system keeps running unchanged — DreamFactory generates a REST API layer in front of it, so there is no risky migration or rewrite.
Which legacy systems can be wrapped?
Legacy Oracle, AS/400, SQL Server, and mainframe-fed databases among others — if the data is reachable, DreamFactory can generate governed REST endpoints for it.
How is security added to systems that predate modern auth?
The API layer applies JWT, OAuth, role-based access control, and rate limiting in front of the legacy system, and logs every call with user identity for auditability.
Has this worked for real mainframe systems?
Yes. The Vermont Department of Transportation bridged a 1970s IBM S/370 mainframe to modern Oracle databases with DreamFactory as the integration layer, across a multi-year modernization program.
