Migration Guide: Download to Service Model

Overview of the Transition

DragonFire is evolving from a traditional download-based software model to a modern service-based architecture. This transition brings significant benefits:

Key Benefits of the Service Model

Migration Path Overview

The recommended migration path consists of five key phases:

Phase 1: Assessment

Begin by thoroughly evaluating your current implementation to create an effective migration plan:

// Install the dependency analyzer
npm install @dragonfire/dependency-analyzer

// Run the analyzer on your codebase
const { DepAnalyzer } = require('@dragonfire/dependency-analyzer');

const analyzer = new DepAnalyzer({
  scanPath: './src',
  includeNodeModules: false,
  generateReport: true,
  reportFormat: 'html'
});

// Analyze dependencies
analyzer.analyze()
  .then(results => {
    console.log('Analysis complete!');
    console.log(`Found ${results.components.length} DragonFire components`);
    console.log(`Generated report at ${results.reportPath}`);
    
    // Display migration complexity estimate
    console.log('Migration complexity estimate:');
    console.log(`- Low complexity components: ${results.complexity.low}`);
    console.log(`- Medium complexity components: ${results.complexity.medium}`);
    console.log(`- High complexity components: ${results.complexity.high}`);
    
    // Estimated migration time
    console.log(`Estimated migration time: ${results.estimatedTime} hours`);
  })
  .catch(err => {
    console.error('Analysis failed:', err);
  });

Phase 2: Authentication Transition

The next step is to migrate from local authentication to the service-based RWT (Rotational WebSockets) authentication system:

// Old approach (local authentication)
import { LocalAuth } from '@dragonfire/local-auth';

// Initialize local authentication
const auth = new LocalAuth({
  configPath: './config/auth.json',
  keyFile: './secure/private.key',
  encryptionLevel: 'high'
});

// Authenticate user
const session = await auth.authenticate({
  username: 'user@example.com',
  password: 'password123'
});

// Use authenticated session
if (session.valid) {
  const kernel = await createKernelInstance(session.token);
  // ... continue with local operations
}

// New approach (service authentication)
import { DragonFireClient } from '@dragonfire/client';
import { RWTClient } from '@dragonfire/rwt-client';

// Initialize core client
const dragonfire = new DragonFireClient({
  apiKey: 'YOUR_API_KEY',
  region: 'us-west'
});

// Initialize RWT client for authentication
const rwt = new RWTClient(dragonfire);

// Connect to authentication service
await rwt.connect('auth-service');

// Create secure authentication channel
const authChannel = await rwt.createSecureChannel({
  purpose: 'authentication',
  encryptionLevel: 'maximum'
});

// Authenticate user
const authResult = await authChannel.request({
  action: 'AUTHENTICATE',
  credentials: {
    email: 'user@example.com',
    password: 'password123'
  }
});

// Use authenticated session
if (authResult.success) {
  // Store the token securely
  localStorage.setItem('df_auth_token', authResult.token);
  
  // Set token for future requests
  dragonfire.setAuthToken(authResult.token);
  
  // Set up automatic token rotation
  rwt.setupTokenRotation({
    token: authResult.token,
    interval: 300000, // 5 minutes
    pattern: 'phi'    // Phi-resonant rotation pattern
  });
  
  // Continue with service operations
}

Phase 3: Core Operations Migration

Replace local processing operations with equivalent service-based API calls:

// Old approach (local kernel)
import { LocalKernel } from '@dragonfire/local-kernel';

// Initialize local kernel
const kernel = new LocalKernel({
  configPath: './config/kernel.json',
  dimensions: 7,
  resourceAllocation: {
    memory: '2GB',
    computeThreads: 4
  }
});

// Execute a local operation
const result = await kernel.execute({
  pattern: 'phi',
  operation: 'transform',
  data: inputData,
  precision: 'high'
});

// New approach (service kernel)
import { DragonFireClient } from '@dragonfire/client';

// Initialize the core client
const dragonfire = new DragonFireClient({
  apiKey: 'YOUR_API_KEY',
  region: 'us-west'
});
await dragonfire.connect();

// Access the kernel service
const kernel = dragonfire.kernel;

// Execute the same operation through the service
const result = await kernel.execute({
  pattern: 'phi',
  dimensions: 7,
  operation: 'transform',
  data: inputData,
  options: {
    precision: 'high',
    optimization: 'maximum'
  }
});

// Old approach (local cache)
import { LocalCache } from '@dragonfire/local-cache';

// Initialize local cache
const cache = new LocalCache({
  cachePath: './data/cache',
  maxSize: '500MB',
  evictionPolicy: 'lru'
});

// Store data in local cache
await cache.set('user_profile_123', userData, {
  ttl: 3600,
  priority: 'high'
});

// Retrieve data from local cache
const cachedData = await cache.get('user_profile_123');

// New approach (service cache)
import { DragonFireClient } from '@dragonfire/client';

// Initialize the core client
const dragonfire = new DragonFireClient({
  apiKey: 'YOUR_API_KEY',
  region: 'us-west'
});
await dragonfire.connect();

// Access the cache service
const cache = dragonfire.cache;

// Store data in service cache
await cache.set('user_profile_123', userData, {
  ttl: 3600,
  pattern: 'fractal',
  priority: 'high',
  sync: true
});

// Retrieve data from service cache
const cachedData = await cache.get('user_profile_123');

// Old approach (local processing)
import { DragonHeart } from '@dragonfire/local-heart';
import { DragonCube } from '@dragonfire/local-cube';

// Initialize local components
const heart = new DragonHeart({
  configPath: './config/heart.json',
  optimizationLevel: 'high'
});

const cube = new DragonCube({
  configPath: './config/cube.json',
  dimensions: 3,
  centerDimensions: 7
});

// Process data locally
const heartResult = await heart.process({
  sequence: dataSequence,
  pattern: 'fibonacci',
  resonance: 'phi'
});

// Transform with local cube
const transformedData = await cube.execute({
  operation: 'transform',
  input: heartResult,
  transformationType: 'jitterbug'
});

// New approach (service processing)
import { DragonFireClient } from '@dragonfire/client';

// Initialize the core client
const dragonfire = new DragonFireClient({
  apiKey: 'YOUR_API_KEY',
  region: 'us-west'
});
await dragonfire.connect();

// Access service components
const heart = dragonfire.heart;
const cube = dragonfire.cube;

// Process data with service
const heartResult = await heart.process({
  sequence: dataSequence,
  pattern: 'fibonacci',
  resonance: 'phi',
  dimensions: 7
});

// Initialize and use a compute cube
const computeCube = await cube.initialize({
  dimensions: 3,
  centerDimensions: 7,
  optimizationPattern: 'phi'
});

// Transform with service cube
const transformedData = await computeCube.execute({
  operation: 'transform',
  input: heartResult,
  transformationType: 'jitterbug'
});

Phase 4: Data Synchronization

Implement secure data transfer between existing local data and cloud services:

import { DragonFireClient } from '@dragonfire/client';
import { MigrationTool } from '@dragonfire/migration-tools';
import { Merlin } from '@dragonfire/merlin-sdk';
import * as fs from 'fs';

async function migrateData() {
  // Initialize the core client
  const dragonfire = new DragonFireClient({
    apiKey: 'YOUR_API_KEY',
    region: 'us-west'
  });
  await dragonfire.connect();
  
  // Initialize migration tool
  const migrationTool = new MigrationTool({
    sourceType: 'local',
    sourcePath: './data',
    targetType: 'service',
    targetService: dragonfire,
    compressionEnabled: true
  });
  
  // Initialize Merlin for data compression
  const merlin = new Merlin({
    apiKey: 'YOUR_API_KEY',
    useCloud: true
  });
  
  // Define data migration mappings
  const mappings = [
    {
      sourcePattern: 'users/*.json',
      targetCollection: 'users',
      transform: (data) => {
        // Transform user data to new format
        return {
          id: data.userId,
          profile: {
            name: data.name,
            email: data.email,
            preferences: data.settings || {}
          },
          metadata: {
            migrated: true,
            migrationDate: new Date().toISOString()
          }
        };
      }
    },
    {
      sourcePattern: 'transactions/*.json',
      targetCollection: 'financial_records',
      transform: (data) => {
        // Transform transaction data
        return {
          transactionId: data.id,
          amount: data.amount,
          currency: data.currency || 'USD',
          timestamp: data.date,
          parties: {
            sender: data.from,
            recipient: data.to
          },
          metadata: {
            migrated: true,
            originalReference: data.reference || null
          }
        };
      }
    },
    {
      sourcePattern: 'analytics/*.json',
      targetCollection: 'insights',
      // Compress large analytics data
      preProcess: async (data) => {
        if (JSON.stringify(data).length > 1024 * 1024) { // If > 1MB
          const compressed = await merlin.compress(JSON.stringify(data), {
            level: 'high',
            mode: 'text'
          });
          return {
            compressed: true,
            data: compressed.data,
            originalSize: JSON.stringify(data).length,
            compressionRatio: compressed.ratio
          };
        }
        return data;
      }
    }
  ];
  
  // Configure migration
  migrationTool.setMappings(mappings);
  
  // Execute migration with progress reporting
  const result = await migrationTool.migrate({
    batchSize: 100,
    validateEach: true,
    continueOnError: true,
    progressCallback: (progress) => {
      console.log(`Migration progress: ${progress.percentage.toFixed(2)}%`);
      console.log(`Processed ${progress.current} of ${progress.total} items`);
    }
  });
  
  // Generate migration report
  const report = migrationTool.generateReport();
  fs.writeFileSync('./migration-report.json', JSON.stringify(report, null, 2));
  
  console.log('Migration complete!');
  console.log(`Successfully migrated: ${result.success} items`);
  console.log(`Failed: ${result.failed} items`);
  console.log(`Validation errors: ${result.validationErrors}`);
  
  return result;
}

Phase 5: Complete Transition

Finalize service integration, perform validation testing, and decommission download components:

import { DragonFireClient } from '@dragonfire/client';
import { TestSuite } from '@dragonfire/testing';
import { ServiceMonitor } from '@dragonfire/monitoring';

async function completeTransition() {
  // Initialize the core client
  const dragonfire = new DragonFireClient({
    apiKey: 'YOUR_API_KEY',
    region: 'us-west'
  });
  await dragonfire.connect();
  
  // Run comprehensive test suite
  const testSuite = new TestSuite({
    targetService: dragonfire,
    testCases: './tests/service-migration',
    outputPath: './reports/migration-tests',
    timeout: 300000 // 5 minutes
  });
  
  const testResults = await testSuite.runAll();
  
  if (testResults.failedTests.length > 0) {
    console.error(`${testResults.failedTests.length} tests failed!`);
    for (const failure of testResults.failedTests) {
      console.error(`- ${failure.name}: ${failure.error}`);
    }
    throw new Error('Migration validation failed');
  }
  
  console.log(`All ${testResults.passedTests.length} tests passed!`);
  
  // Set up service monitoring
  const monitor = new ServiceMonitor({
    service: dragonfire,
    metrics: [
      'requestLatency',
      'errorRate',
      'throughput',
      'availability',
      'resourceUtilization'
    ],
    alertThresholds: {
      errorRate: 0.01, // Alert if error rate exceeds 1%
      latency: 500,    // Alert if latency exceeds 500ms
      availability: 0.995 // Alert if availability drops below 99.5%
    },
    reporting: {
      interval: 300000, // 5 minutes
      destinations: ['dashboard', 'email', 'webhook']
    }
  });
  
  await monitor.start();
  console.log('Service monitoring active');
  
  // Archive local data
  console.log('Archiving local data...');
  // [Archive code here]
  
  console.log('Migration complete!');
  
  return {
    status: 'complete',
    testResults: {
      total: testResults.passedTests.length + testResults.failedTests.length,
      passed: testResults.passedTests.length,
      failed: testResults.failedTests.length
    },
    monitoring: {
      active: true,
      metrics: monitor.getActiveMetrics()
    }
  };
}
