# Migrating .NET Data Access Code from Oracle to PostgreSQL
Migrate the C# data access layer of a single `.Postgres`-copy project from Oracle (Oracle.ManagedDataAccess) to PostgreSQL (Npgsql). Work item by item through `Reports/{ProjectName}/MigrationChecklist.md`.
## Prerequisites
- The `.Postgres` project copy exists (created in Phase 5 setup).
- `Reports/{ProjectName}/MigrationChecklist.md` exists and is the source of truth for what to change.
- `Reports/{ProjectName}/OracleRiskAnalysis.md` exists for cross-referencing behavioral differences.
## Workflow
