Check Migration Status Skill

When the user invokes /check-migration-status:

Overview

This skill audits the migration progress from legacy MVC (Neptune.WebMvc) to Angular SPA (Neptune.Web) + ASP.NET Core API (Neptune.API). It identifies which entities have been migrated, which are in progress, and which still need migration.

Steps to Execute

1. Inventory Legacy Controllers

List all controllers in the legacy MVC project:

code

Neptune.WebMvc/Controllers/

For each controller, gather:

•Controller name (e.g., TreatmentBMPController.cs)
•Number of action methods (complexity indicator)
•Number of views in Neptune.WebMvc/Views/{Entity}/

Exclude infrastructure controllers (not domain entities):

•AccountController
•HomeController
•NeptuneBaseController
•ErrorController
•Any controller that doesn't represent a domain entity

2. Inventory New API Controllers

List all controllers in the new API project:

code

Neptune.API/Controllers/

Note which entity each controller handles.

3. Inventory Angular Pages

List all page components in:

code

Neptune.Web/src/app/pages/

Check Neptune.Web/src/app/app.routes.ts for registered routes.

4. Compare and Analyze

Create a migration status for each entity:

Status	Meaning
Migrated	Has API controller + Angular page + routes
Partial	Has API controller but missing Angular page (or vice versa)
Not Started	Only exists in legacy MVC
New Only	Only exists in new stack (no legacy equivalent)

5. Generate Report

Output a markdown table with the following columns:

Entity	Legacy Controller	Legacy Views	API Controller	Angular Page	Status	Priority

6. Priority Assessment

For unmigrated entities, suggest priority based on:

•High: Core business entities (TreatmentBMP, Project, OnlandVisualTrashAssessment, WaterQualityManagementPlan)
•Medium: Supporting entities with moderate complexity (LandUseBlock, Delineation, TrashGeneratingUnit)
•Low: Simple lookup/reference entities

Also consider:

•Dependencies on other entities (migrate dependencies first)
•User impact (frequently used pages = higher priority)
•Complexity (simpler entities = quick wins)

7. Recommendations

After the status table, provide:

•Quick wins: Simple entities that can be migrated quickly
•Dependencies: Entities that should be migrated in a specific order
•Complex migrations: Entities requiring significant effort (workflows, maps, complex grids)

Output Format

# Migration Status Report

Generated: {current date}

## Summary
- Total Legacy Controllers: X
- Migrated: Y
- Partial: Z
- Not Started: W

## Detailed Status

| Entity | Legacy | Views | API | Angular | Status | Priority |
|--------|--------|-------|-----|---------|--------|----------|
| TreatmentBMP | Yes | 12 | Yes | Yes | Migrated | - |
| Project | Yes | 8 | Yes | Partial | Partial | High |
| OVTA | Yes | 5 | No | No | Not Started | High |
| ... | ... | ... | ... | ... | ... | ... |

## Recommendations

### Quick Wins (Low Complexity, High Value)
1. {EntityName} - {reason}

### Dependencies to Address First
1. {EntityName} should be migrated before {OtherEntity}

### Complex Migrations (Plan Carefully)
1. {EntityName} - {complexity factors: workflow, maps, large grid, etc.}

Notes

•Ignore controllers that are infrastructure-related (Home, Account, Error, etc.)
•Focus on domain entity controllers
•Check for [Obsolete] markers on legacy controllers (already migrated)
•Consider shared components that may need to be created first
