Unstructured Legacy Data Access and Migration

Discover, access, stream, and migrate IMS-DB and VSAM data using approved layouts and a shared catalog.

Challenges

  • IMS-DB and VSAM layouts are inspected on green screens instead of a shared, approved catalog.
  • Teams lack a governed path to browse, query, and update IMS hierarchies and VSAM records under RACF.
  • Streaming changes and migrating VSAM to SQL still depends on custom extract jobs, hand-written DDL, and disconnected lineage.

Benefits

  • Discover IMS-DB and VSAM sources in AtomIQ and bind COBOL layouts in CoreIQ catalogs for governed access.
  • Browse, query, and where gated update IMS segments and VSAM KSDS records under the caller’s RACF identity.
  • Stream VSAM changes to Kafka or webhooks and migrate schemas and records into SQL with persisted field-to-column lineage.

This capability brings IMS-DB and VSAM assets into a shared modernization workflow. AtomIQ can be used to discover data sources, while CoreIQ catalogs preserve approved layout associations so teams can work from governed definitions instead of ad hoc green-screen inspection or separate tooling.
