CASE STUDY / Database migration

SQL Server to PostgreSQL migration within the working day.

A representative financial-services development-platform migration where compatibility remediation, data movement, permissions and application readiness were treated as one delivery workstream.

Challenge, approach and acceptance.

Context

A development platform needed to move from Microsoft SQL Server to PostgreSQL without stalling the application team or leaving target-platform issues for later.

Constraint

The migration had to preserve delivery momentum and surface compatibility differences quickly enough to remediate them inside the planned working window.

Approach

Schema and data migration, SQL/data-type compatibility, access/permissions, application coordination and validation were handled together rather than as disconnected hand-offs.

Acceptance

The PostgreSQL environment was available to the development team within the same working day, with the target validated for continued development.

Migration decisions were constrained by application compatibility, delivery timing, validation evidence, rollback readiness and the target team’s ability to operate PostgreSQL.
