Put your IMS and VSAM data to work

Discover, access, update, stream, and migrate IMS-DB and VSAM data from approved layouts in one governed catalog. Replace green-screen inspection, custom extract jobs, and hand-written DDL with APIs, event pipelines, and SQL migration your teams can repeat.

Why mainframe data stays hard to use

IMS-DB and VSAM hold decades of customer, policy, and transaction records. Yet most teams still reach that data through green screens and one-off scripts.

No shared, approved layouts

IMS-DB and VSAM layouts are inspected on green screens instead of a shared, approved catalog.

No governed access path

Teams lack a governed path to browse, query, and update IMS hierarchies and VSAM records under RACF.

Custom jobs for streaming & migration

Streaming changes and migrating VSAM to SQL still depends on custom extract jobs, hand-written DDL, and disconnected lineage.

A governed path from discovery to migration

OpenLegacy brings IMS-DB and VSAM into one modernization workflow. Modernization and integration teams get one governed way to work with legacy data, built on trusted mainframe structures.

You rely less on green-screen tools, custom extract jobs, hand-written DDL, and lineage tracked in spreadsheets, and you feed APIs, event pipelines, and SQL targets from the same approved definitions.

Governed access from one catalog

Discover IMS-DB and VSAM sources and bind COBOL layouts in one catalog, so every consumer works from approved definitions.

Read and write under RACF

Browse, query, and, where write access is enabled, update IMS segments and VSAM KSDS records under the caller's own RACF identity.

Streaming and SQL migration with lineage

Stream VSAM changes to Kafka or webhooks, and migrate schemas and records into SQL with field-to-column lineage saved along the way.
