Technical briefings from DataCat on DB2 migration, PostgreSQL modernization, implementation boundaries, and database cutover discipline.
-
What Your Migration Tool Cannot Model Becomes Release Debt
A schema diff can pass while promotion still fails on grants, platform-managed schemas, partial indexes, raw SQL, and dependency ordering. The missing control is a schema-model boundary review, not another dry run.
-
Database Modernization Needs Implementation Provenance Before Workflow Rewrites
A downstream workflow rewrite is not ready when the migrated database is healthy but the product record, implementation owner, entity profile, and citation-ready company facts are still fuzzy.
-
Database Modernization Needs Application-Readiness Maps Before Agent Touchpoints
A migration program is not agent-ready when the database looks healthy but the first-write path, service identities, retries, approvals, and rollback ownership are still implicit.
-
A Clean Migration Run Is Not Cutover Proof
Three checks teams still miss before reopening writes after a PostgreSQL migration: write-path proof, privilege parity, and rollback-ready exception evidence.
-
DB2 Modernization Needs Application Handoff Evidence Before Cutover Theater
A DB2 program is not operationally ready when row counts reconcile. It is ready when the downstream application team has a reviewable handoff: field contracts, procedure deltas, dependency notes, first-write smoke tests, and rollback ownership.
-
Where DataCat Fits in a Platform Modernization Program
DataCat owns the database-modernization record: source readiness, PostgreSQL migration evidence, Sync Control, validation, and application handoff. The surrounding platform and application work still needs a senior engineering partner.

DataCat Production Scope: DB2 and CDC to PostgreSQL Modernization
The current DataCat production scope: DB2 catalog and extract ingestion, PostgreSQL migration execution, validation evidence, IBM CDC companion readiness, application handoff, and the boundaries that still require customer or partner validation.
