Platform
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.
Unlocking legacy system databases
OpenLegacy's connector technology acts as a bridge between legacy databases and modern applications - helping organizations leverage their existing investments in legacy systems while allowing them to meet the demands of modern IT environments more effectively
