+# Migration Guide: AutoGen 0.4 → Microsoft Agent Framework
+
+This document explains the migration from AutoGen 0.4 to Microsoft Agent Framework performed on this repository.
+
+## Overview
+
+**Microsoft Agent Framework** is the successor to AutoGen, combining the best of AutoGen's multi-agent orchestration with enhanced enterprise features. AutoGen is now in maintenance mode (security fixes only), while Microsoft Agent Framework is actively developed.
+
+## What Changed
+
+### 1. Dependencies (requirements.txt)
+
+**Before:**
+```
+autogen-agentchat==0.4.8
+autogen-ext[openai,azure,docker]==0.4.8
+python-dotenv
+rich
+```
+
+**After:**
+```
+agent-framework
+azure-identity
+python-dotenv
+rich
+requests
+```
+
+### 2. Imports
+
+**Before:**
+```python
+from autogen_agentchat.agents import AssistantAgent, UserProxyAgent
+from autogen_agentchat.teams import SelectorGroupChat
+from autogen_agentchat.conditions import TextMentionTermination
+from autogen_ext.models.openai import AzureOpenAIChatCompletionClient
+```
+
+**After:**
+```python
+from agent_framework import ChatAgent
+from agent_framework.azure import AzureOpenAIChatClient
+from azure.identity import DefaultAzureCredential
+```
+
+### 3. Agent Creation
+
+**Before:**
+```python
+agent = AssistantAgent(
+    name="writer",
+    description="...",
+    model_client=AzureOpenAIChatCompletionClient(
+        model=model_name,
+        api_version=api_version,
+        azure_endpoint=endpoint,
+        api_key=key,
+        model_capabilities={...}
+    ),
+    system_message="...",
+    tools=[...]
+)
+```
+
+**After:**
+```python
+chat_client = AzureOpenAIChatClient(
+    endpoint=endpoint,
+    model=model_name,
+    api_version=api_version,
+    api_key=key,
+    # OR use Azure CLI credentials:
+    # credential=DefaultAzureCredential()
+)
+
+agent = ChatAgent(
+    name="writer",
+    description="...",
+    chat_client=chat_client,
+    instructions="...",  # replaces system_message
+    tools=[...]
+)
+```
+
+### 4. Group Chat Orchestration
+
+**Before (AutoGen):**
+```python
+team = SelectorGroupChat(
+    agents=[agent1, agent2, ...],
+    model_client=model_client,
+    termination_condition=TextMentionTermination("TERMINATE")
+)
+
+stream = team.run_stream(task=prompt)
+async for response in stream:
+    # Handle response
+```
+
+**After (Microsoft Agent Framework):**
+```python
+# Custom orchestration loop
+messages = []
+while conversation_active:
+    # Orchestrator selects next speaker
+    selector_prompt = "Based on conversation, who should speak next?"
+    result = await orchestrator_agent.run(messages=messages + [selector_prompt])
+    next_speaker = result.text
+
+    # Find and run the selected agent
+    current_agent = find_agent(next_speaker)
+    result = await current_agent.run(messages=messages)
+    messages.append({"role": "assistant", "name": current_agent.name, "content": result.text})
+
+    # Check for termination
+    if "TERMINATE" in result.text:
+        break
+```
+
+## Key Differences
+
+### Architecture
+
+| Feature | AutoGen 0.4 | Microsoft Agent Framework |
+|---------|-------------|---------------------------|
+| Group Chat | Built-in `SelectorGroupChat` | Custom orchestration required |
+| Agent Types | `AssistantAgent`, `UserProxyAgent` | `ChatAgent` |
+| Model Client | `AzureOpenAIChatCompletionClient` | `AzureOpenAIChatClient` |
+| Instructions | `system_message` parameter | `instructions` parameter |
+| Authentication | API key only | API key or Azure CLI credentials |
+| Message Handling | Event-driven streaming | Message list with run() method |
+
+### Benefits of Microsoft Agent Framework
+
+1. **Active Development**: New features and improvements ongoing
+2. **Better Authentication**: Support for Azure CLI and managed identities
+3. **Unified Framework**: Combines AutoGen and Semantic Kernel concepts
+4. **Enterprise Ready**: Enhanced observability, security, and governance
+5. **Multi-language**: Python and .NET support
+
+## Migration Checklist
+
+- [x] Update requirements.txt with new packages
+- [x] Replace AutoGen imports with Microsoft Agent Framework imports
+- [x] Convert `AssistantAgent` → `ChatAgent`
+- [x] Update model client initialization
+- [x] Replace `system_message` with `instructions`
+- [x] Implement custom group chat orchestration
+- [x] Remove `UserProxyAgent` (handle user input directly)
+- [x] Update termination logic
+- [x] Test authentication (Azure CLI or API key)
+- [x] Validate functionality
+
+## Testing
+
+Run the validation script to ensure migration was successful:
+
+```bash
+python test_migration.py
+```
+
+This validates:
+- ✅ All imports work correctly
+- ✅ Script syntax is valid
+- ✅ Tool functions are properly defined
+- ✅ Environment variables are configured
+
+## Running the Migrated Code
+
+### Prerequisites
+
+1. Azure OpenAI resource with GPT-4o deployment
+2. Bing Search API key (optional, for web search)
+3. Python 3.8+
+
+### Installation
+
+```bash
+# Create and activate environment
+conda create --name research -y
+conda activate research
+
+# Install dependencies
+pip install -r requirements.txt
+
+# Authenticate with Azure CLI (recommended)
+az login
+
+# OR set API key in .env file
+# AZURE_OPENAI_API_KEY=your_key_here
+```
+
+### Run
+
+```bash
+# Journalism research
+python journalism_research.py
+
+# Product shopping research  
+python shopping.py
+```
+
+## Troubleshooting
+
+### Import Errors
+
+If you get import errors, ensure agent-framework is installed:
+```bash
+pip install agent-framework --upgrade
+```
+
+### Authentication Issues
+
+**Azure CLI Method (Recommended):**
+```bash
+az login
+az account set --subscription "your-subscription-id"
+```
+
+**API Key Method:**
+Add to .env file:
+```
+AZURE_OPENAI_API_KEY=your_key_here
+```
+
+### Agent Not Responding
+
+The custom orchestration loop may need tuning. Check:
+- Orchestrator agent instructions are clear
+- Agent names match exactly in selector logic
+- Message history is maintained properly

+## Migration to Microsoft Agent Framework
+This codebase has been migrated from AutoGen 0.4 to Microsoft Agent Framework. Key changes include:
+- Updated from `autogen-agentchat` to `agent-framework` packages
+- Agents now use `ChatAgent` from Microsoft Agent Framework
+- Azure OpenAI integration via `AzureOpenAIChatClient`
+- Custom group chat orchestration (MAF doesn't have direct SelectorGroupChat equivalent)
+- Simplified authentication with Azure CLI or API key fallback
+
+### Authentication
+The code supports two authentication methods:
+1. **Azure CLI (Recommended)**: Run `az login` before executing the script
+2. **API Key**: Set `AZURE_OPENAI_API_KEY` in your .env file
