Overview

The Logic Apps Migration Agent is a VS Code extension that automates the migration of enterprise integration solutions to Azure Logic Apps Standard. It uses AI-powered analysis via GitHub Copilot to guide you through a structured migration workflow — all running locally within VS Code.

Supported Source Platforms

This is an open-source project — contributions are welcome! To add support for a new platform, see Contributing a New Platform.

Target Platform

• Azure Logic Apps Standard (Workflow Service Plan)

Features

Migration Stages

The extension guides you through a 5-stage migration workflow:

Discovery → Planning → Conversion → Validation → Deployment

Quick Start

1. Install the extension from VS Code Marketplace
2. Open your BizTalk or MuleSoft project folder in VS Code
3. Click the Logic Apps Migration Agent icon in the Activity Bar
4. Select your source folder when prompted (or use the command palette: Logic Apps Migration Agent: Select Source Folder)
5. Follow the guided 5-stage workflow

Architecture

Parser System

Parsers are TypeScript modules that transform source platform artifacts into a common Intermediate Representation (IR). The extension uses a registry-based architecture supporting both built-in and external parsers.

AI Agents

The extension provisions three GitHub Copilot agents into your workspace:

LM Tools

The extension registers 25 Language Model tools with VS Code that the AI agents use to read artifacts, store results, and manage the migration workflow.

Source Flow Visualization

The Flow Visualizer provides an interactive webview for exploring your integration architecture. It displays data from parsed IR documents, bindings, dependency graphs, and AI-generated analysis.

Visualization Tabs

Diagram Features

• Interactive Mermaid diagrams with zoom/pan
• Dark/light theme support
• Copilot chat integration — discuss or correct any flow group
• Badge indicators for gaps, dependencies, and patterns

Contributing a New Platform

This project is open-source and designed for extensibility. There are two ways to add support for a new integration platform:

Built-in parsers are the recommended approach — they ship with the extension, get the same CI/CD, and have access to all internal APIs.

What You Need to Add

To fully support a new platform (e.g., TIBCO, IBM IIB, Workato), you need:

1. A built-in parser — parses source artifacts into IR documents
2. Platform-specific skills — AI instructions for each migration stage
3. Platform detection — auto-detect the platform from file patterns

Step 1: Add a Built-in Parser

Create a new parser under src/parsers/<platform>/:

src/parsers/
├── biztalk/           # Reference implementation
│   ├── index.ts
│   ├── types.ts
│   ├── BizTalkProjectParser.ts
│   ├── BizTalkOrchestrationParser.ts
│   └── ...
├── <your-platform>/   # Your new parser
│   ├── index.ts
│   ├── types.ts
│   └── YourPlatformParser.ts

Each parser must implement the IParser interface:

import { IParser, ParserCapabilities, ParseResult, ParseOptions } from '../types';
import { IRDocument, createEmptyIRDocument } from '../../ir/types';

export class YourPlatformParser implements IParser {
    get capabilities(): ParserCapabilities {
        return {
            platform: 'your-platform',
            fileExtensions: ['.yourext'],
            fileTypes: ['flow'],
            supportsFolder: false,
            description: 'Parses YourPlatform integration flows',
        };
    }

    canParse(filePath: string): boolean {
        return filePath.endsWith('.yourext');
    }

    async parse(filePath: string, options?: ParseOptions): Promise<ParseResult> {
        const ir = createEmptyIRDocument();
        // Parse the source file and populate the IR document
        // See docs/IRSchema.md for the complete schema
        // See docs/IRExamples_*.md for platform-specific examples
        return { ir, stats: { ... } };
    }
}

Then register it in src/parsers/index.ts:

import { YourPlatformParser } from './your-platform';

export function initializeParsers(): void {
    // ... existing parsers ...
    defaultParserRegistry.register(new YourPlatformParser());
}

Reference: See the BizTalk parser implementation in src/parsers/biztalk/ for a fully working example.

Step 2: Add Platform-Specific Skills

Skills are Markdown files that provide AI instructions for each stage of the migration. They tell the Copilot agents how to analyze, plan, and convert artifacts for your specific platform.

Skills are organized under resources/skills/, with platform-specific variants:

resources/skills/
├── detect-logical-groups/
│   ├── biztalk/SKILL.md          # BizTalk-specific rules
│   ├── mulesoft/SKILL.md         # MuleSoft-specific rules
│   └── <your-platform>/SKILL.md  # Your platform rules
├── source-to-logic-apps-mapping/
│   ├── biztalk/SKILL.md
│   ├── mulesoft/SKILL.md
│   └── <your-platform>/SKILL.md
└── ... (13 skills total)

Skill Format

Each SKILL.md uses YAML frontmatter followed by Markdown content:

---
name: source-to-logic-apps-mapping
description: One-to-one mapping of every YourPlatform component to its Azure Logic Apps Standard equivalent.
---

# YourPlatform to Azure Logic Apps Standard — Component Migration Reference

> Mapping of YourPlatform components to Logic Apps equivalents.

## Adapter Mappings

| YourPlatform Component | Logic Apps Equivalent | Native? | Notes           |
| ---------------------- | --------------------- | ------- | --------------- |
| HTTP Listener          | HTTP Trigger          | Yes     | Native built-in |
| Database Connector     | SQL Server connector  | Yes     | Native built-in |

...

Required Skills (13 total)

You should create a <your-platform>/SKILL.md variant for each of these skills:

Tip: Copy an existing platform's skills as a starting point (e.g., biztalk/SKILL.md) and adapt the content for your platform.

Step 3: Register the Platform

Add your platform to the supported platforms list in src/types/platforms.ts:

export type SourcePlatform = 'biztalk' | 'mulesoft' | 'your-platform';

export const SUPPORTED_PLATFORMS: PlatformInfo[] = [
    // ... existing platforms ...
    {
        id: 'your-platform',
        label: 'YourPlatform',
        description: 'YourPlatform version X',
        icon: '$(server)',
        filePatterns: ['.yourext', '.yourconfig'],
    },
];

Also add detection logic in src/stages/discovery/PlatformDetector.ts and file patterns in src/stages/discovery/SourceFolderService.ts.

Step 4: Add IR Examples (Optional but Recommended)

Add a docs/IRExamples_YourPlatform.md documenting how your platform's artifacts map to the IR schema. The existing examples serve as templates:

• docs/IRExamples_BizTalk.md — BizTalk reference
• docs/IRExamples_MuleSoft.md — MuleSoft reference
• docs/IRExamples_Boomi.md — Dell Boomi example
• docs/IRExamples_IBMIIB.md — IBM IIB/ACE example
• docs/IRExamples_TIBCO.md — TIBCO BusinessWorks example
• docs/IRExamples_Workato.md — Workato example

Alternative: External Parser Extension

If you prefer not to contribute directly to this repo, you can create a separate VS Code extension that registers parsers via the plugin API:

import * as vscode from 'vscode';

export async function activate(context: vscode.ExtensionContext) {
    const assistant = vscode.extensions.getExtension('microsoft.logicapps-migration-assistant');

    if (assistant) {
        const api = await assistant.activate();
        api.registerParser(new MyPlatformParser(), { priority: 10 });
    }
}

Note: External parser extensions only cover the Discovery stage (parsing source files). Skills, platform detection, and AI-powered planning/conversion require contributing to this repo directly.

Parser Plugin API

IR Schema

All parsers must output documents conforming to the IR (Intermediate Representation) schema. See docs/IRSchema.md for the complete specification.
