Groq Migration Deep Dive

Overview

Comprehensive guide for migrating to or from Groq, or major version upgrades.

Prerequisites

• Current system documentation
• Groq SDK installed
• Feature flag infrastructure
• Rollback strategy tested

Migration Types

Type	Complexity	Duration	Risk
Fresh install	Low	Days	Low
From competitor	Medium	Weeks	Medium
Major version	Medium	Weeks	Medium
Full replatform	High	Months	High

Pre-Migration Assessment

Step 1: Current State Analysis

set -euo pipefail
# Document current implementation
find . -name "*.ts" -o -name "*.py" | xargs grep -l "groq" > groq-files.txt

# Count integration points
wc -l groq-files.txt

# Identify dependencies
npm list | grep groq
pip freeze | grep groq

Step 2: Data Inventory

interface MigrationInventory {
  dataTypes: string[];
  recordCounts: Record<string, number>;
  dependencies: string[];
  integrationPoints: string[];
  customizations: string[];
}

async function assessGroqMigration(): Promise<MigrationInventory> {
  return {
    dataTypes: await getDataTypes(),
    recordCounts: await getRecordCounts(),
    dependencies: await analyzeDependencies(),
    integrationPoints: await findIntegrationPoints(),
    customizations: await documentCustomizations(),
  };
}

Migration Strategy: Strangler Fig Pattern

Phase 1: Parallel Run
┌─────────────┐     ┌─────────────┐
│   Old       │     │   New       │
│   System    │ ──▶ │  Groq   │
│   (100%)    │     │   (0%)      │
└─────────────┘     └─────────────┘

Phase 2: Gradual Shift
┌─────────────┐     ┌─────────────┐
│   Old       │     │   New       │
│   (50%)     │ ──▶ │   (50%)     │

Phase 3: Complete

Implementation Plan

Phase 1: Setup (Week 1-2)

set -euo pipefail
# Install Groq SDK
npm install @groq/sdk

# Configure credentials
cp .env.example .env.groq
# Edit with new credentials

# Verify connectivity
node -e "require('@groq/sdk').ping()"

Phase 2: Adapter Layer (Week 3-4)

// src/adapters/groq.ts
interface ServiceAdapter {
  create(data: CreateInput): Promise<Resource>;
  read(id: string): Promise<Resource>;
  update(id: string, data: UpdateInput): Promise<Resource>;
  delete(id: string): Promise<void>;
}

class GroqAdapter implements ServiceAdapter {
  async create(data: CreateInput): Promise<Resource> {
    const groqData = this.transform(data);
    return groqClient.create(groqData);
  }

  private transform(data: CreateInput): GroqInput {
    // Map from old format to Groq format
  }
}

Phase 3: Data Migration (Week 5-6)

async function migrateGroqData(): Promise<MigrationResult> {
  const batchSize = 100;
  let processed = 0;
  let errors: MigrationError[] = [];

  for await (const batch of oldSystem.iterateBatches(batchSize)) {
    try {
      const transformed = batch.map(transform);
      await groqClient.batchCreate(transformed);
      processed += batch.length;
    } catch (error) {
      errors.push({ batch, error });
    }

    // Progress update
    console.log(`Migrated ${processed} records`);
  }

  return { processed, errors };
}

Phase 4: Traffic Shift (Week 7-8)

// Feature flag controlled traffic split
function getServiceAdapter(): ServiceAdapter {
  const groqPercentage = getFeatureFlag('groq_migration_percentage');

  if (Math.random() * 100 < groqPercentage) {
    return new GroqAdapter();
  }

  return new LegacyAdapter();
}

Rollback Plan

set -euo pipefail
# Immediate rollback
kubectl set env deployment/app GROQ_ENABLED=false
kubectl rollout restart deployment/app

# Data rollback (if needed)
./scripts/restore-from-backup.sh --date YYYY-MM-DD

# Verify rollback
curl https://app.yourcompany.com/health | jq '.services.groq'

Post-Migration Validation

async function validateGroqMigration(): Promise<ValidationReport> {
  const checks = [
    { name: 'Data count match', fn: checkDataCounts },
    { name: 'API functionality', fn: checkApiFunctionality },
    { name: 'Performance baseline', fn: checkPerformance },
    { name: 'Error rates', fn: checkErrorRates },
  ];

  const results = await Promise.all(
    checks.map(async c => ({ name: c.name, result: await c.fn() }))
  );

  return { checks: results, passed: results.every(r => r.result.success) };
}

Instructions

Assess current configuration

Document existing implementation and data inventory.

Step 2: Build Adapter Layer

Create abstraction layer for gradual migration.

Step 3: Migrate Data

Run batch data migration with error handling.

Step 4: Shift Traffic

Gradually route traffic to new Groq integration.

Output

• Migration assessment complete
• Adapter layer implemented
• Data migrated successfully
• Traffic fully shifted to Groq

Error Handling

Issue	Cause	Solution
Data mismatch	Transform errors	Validate transform logic
Performance drop	No caching	Add caching layer
Rollback triggered	Errors spiked	Reduce traffic percentage
Validation failed	Missing data	Check batch processing

Examples

Quick Migration Status

const status = await validateGroqMigration();
console.log(`Migration ${status.passed ? 'PASSED' : 'FAILED'}`);
status.checks.forEach(c => console.log(`  ${c.name}: ${c.result.success}`));
