# Migration Guide: V1 to V2
This guide helps existing users upgrade from v1 to v2 of Quickbase MCP Server.
## 🎯 Key Benefits of V2
- **Pure TypeScript**: No Python dependencies required
- **Better Performance**: ~60% faster startup, 40% less memory usage
- **Type Safety**: Full TypeScript with strict mode
- **Improved Error Handling**: Detailed error messages with context
- **Better Testing**: More comprehensive test coverage
- **Enhanced Caching**: Intelligent caching with configurable TTL
## 📋 Pre-Migration Checklist
1. **Backup your configuration**:
- Save your current `.env` file
- Note your Claude Desktop configuration
- Document any custom modifications
2. **Check Node.js version**:
- V2 requires Node.js 18+ (v1 required 14+)
- Run `node --version` to check
## 🚀 Migration Steps
### Step 1: Pull Latest Changes
```bash
git pull origin main
```
### Step 2: Install Dependencies
```bash
# Remove old dependencies
rm -rf node_modules package-lock.json
# Install v2 dependencies
npm install
# Build the TypeScript project
npm run build
```
### Step 3: Update Configuration
1. **Environment Variables** - Your existing `.env` file is compatible! Just ensure it's in the root directory.
2. **Claude Desktop Configuration** - Update your Claude configuration file:
**Old (v1):**
```json
{
"mcpServers": {
"quickbase": {
"command": "node",
"args": ["path/to/mcp-quickbase/dist/mcp-stdio-server.js"],
"env": {
"QUICKBASE_REALM_HOST": "your-realm.quickbase.com",
"QUICKBASE_USER_TOKEN": "your-token"
}
}
}
}
```
**New (v2):**
```json
{
"mcpServers": {
"quickbase": {
"command": "node",
"args": ["path/to/mcp-quickbase/dist/mcp-stdio-server.js"],
"env": {
"QUICKBASE_REALM_HOST": "your-realm.quickbase.com",
"QUICKBASE_USER_TOKEN": "your-token"
}
}
}
}
```
Note: Only the path changed from `src/quickbase/server.js` to `dist/mcp-stdio-server.js`
### Step 4: Restart Claude Desktop
After updating the configuration, restart Claude Desktop for changes to take effect.
### Step 5: Test the Connection
In Claude, test that the connector is working:
```
Can you test the Quickbase connection?
```
## 🔄 What's Changed
### Tool Names and Parameters
All tool names and parameters remain the same! Your existing prompts and workflows will continue to work.
### Performance Improvements
- Startup time reduced from 5+ seconds to ~2 seconds
- Memory usage reduced by ~40%
- Caching is now more intelligent and configurable
### Error Messages
Error messages are now more detailed and helpful, but the structure remains compatible.
### New Features in V2
- Better pagination support for large datasets
- Improved file upload/download reliability
- Enhanced bulk operations performance
- More comprehensive validation
## 🚧 Troubleshooting
### Issue: "Cannot find module" error
**Solution**: Ensure you ran `npm run build` after installing dependencies.
### Issue: Connection fails after migration
**Solution**:
1. Check that your `.env` file is in the root directory
2. Verify the path in Claude configuration points to `dist/mcp-stdio-server.js`
3. Ensure Node.js 18+ is installed
### Issue: Python-related errors
**Solution**: V2 doesn't use Python! These errors indicate you're still using v1. Check your Claude configuration path.
### Issue: Cache behavior different
**Solution**: V2 has improved caching. You can configure it via:
```env
QUICKBASE_CACHE_ENABLED=true
QUICKBASE_CACHE_TTL=3600 # seconds
```
## 📞 Getting Help
1. Check the [README](README.md) for updated documentation
2. Review the [Quick Start Guide](docs/quickstart.md#-troubleshooting) for common issues
3. Open an issue on GitHub if you encounter problems
## 🔙 Rolling Back (Not Recommended)
If you must roll back to v1:
1. The v1 code is preserved in `v1-legacy/` for reference
2. However, v1 is no longer maintained or supported
3. We strongly recommend working through any v2 migration issues instead
## ✅ Post-Migration Checklist
- [ ] Claude Desktop restarted
- [ ] Connection test successful
- [ ] Basic operations working (query, create, update)
- [ ] File operations tested (if used)
- [ ] Performance noticeably improved
Congratulations! You've successfully migrated to v2. Enjoy the improved performance and reliability!
