Creating an Oracle-to-PostgreSQL Master Migration Plan

Analyze a .NET solution, classify every project for Oracle→PostgreSQL migration eligibility, and write a structured plan that downstream agents and skills can parse.

Workflow

Progress:
- [ ] Step 1: Discover projects in the solution
- [ ] Step 2: Classify each project
- [ ] Step 3: Confirm with user
- [ ] Step 4: Write the plan file

Step 1: Discover projects

Find the Solution File (it has a .sln or .slnx extension) in the workspace root (ask the user if multiple exist). Parse it to extract all .csproj project references. For each project, note the name, path, and type (class library, web API, console, test, etc.).

Step 2: Classify each project

Scan every non-test project for Oracle indicators:

• NuGet references: Oracle.ManagedDataAccess, Oracle.EntityFrameworkCore (check .csproj and packages.config)
• Config entries: Oracle connection strings in appsettings.json, web.config, app.config
• Code usage: OracleConnection, OracleCommand, OracleDataReader
• DDL cross-references under .github/oracle-to-postgres-migration/DDL/Oracle/ (if present)

Assign one classification per project:

Classification	Meaning
MIGRATE	Has Oracle interactions requiring conversion
SKIP	No Oracle indicators (UI-only, shared utility, etc.)
ALREADY_MIGRATED	A -postgres or .Postgres duplicate exists and appears processed
TEST_PROJECT	Test project; handled by the testing workflow

Step 3: Confirm with user

Present the classified list. Let the user adjust classifications or migration ordering before finalizing.

Step 4: Write the plan file

Save to: .github/oracle-to-postgres-migration/Reports/MasterMigrationPlan.md

Use this exact template — downstream consumers depend on the structure:

# Master Migration Plan

**Solution:** {solution file name}
**Solution Root:** {REPOSITORY_ROOT}
**Created:** {timestamp}
**Last Updated:** {timestamp}

## DDL Artifacts

**Location:** {path to DDL artifacts, e.g., `.github/oracle-to-postgres-migration/DDL/`}
**External tool used:** {Yes / No} — {If Yes, name the tool (e.g., `ora2pg`) and note that Phase 4 (Schema & DDL Migration) can be skipped; PostgreSQL DDL artifacts already exist.}

## Solution Summary

| Metric | Count |
|--------|-------|
| Total projects in solution | {n} |
| Projects requiring migration | {n} |
| Projects already migrated | {n} |
| Projects skipped (no Oracle usage) | {n} |
| Test projects (handled separately) | {n} |

## Project Inventory

| # | Project Name | Path | Classification | Notes |
|---|---|---|---|---|
| 1 | {name} | {relative path} | MIGRATE | {notes} |
| 2 | {name} | {relative path} | SKIP | No Oracle dependencies |

## Migration Order

1. **{ProjectName}** — {rationale, e.g., "Core data access library; other projects depend on it."}
2. **{ProjectName}** — {rationale}

Order projects so that shared/foundational libraries are migrated before their dependents.
