A secure, resumable WordPress migration plugin designed for production-to-staging deployments. Built with DRY & YAGNI principles, focusing on MySQL/MariaDB migrations with robust file synchronization.
WP-Migrate is a WordPress plugin that enables automated, secure migrations between production and staging environments. It's designed for:
- Agencies: Migrate client sites to staging for testing
- Developers: Deploy updates safely with rollback capability
- DevOps: Automate WordPress deployments in CI/CD pipelines
- Site Owners: Maintain staging environments synchronized with production
Phase: Production Ready (100% Complete) ✅ Status: Enterprise-grade migration plugin ready for deployment Test Coverage: 95%+ with 100+ comprehensive tests Security: Bulletproof HMAC authentication with TLS enforcement
- Security: HMAC authentication with shared keys and TLS enforcement
- API: Complete REST endpoint infrastructure with 6 endpoints
- File Management: Chunked uploads with resume support (64MB chunks)
- State Management: Job lifecycle and persistence with 9 states
- Database Engine: Complete MySQL export/import with URL rewriting
- Migration Workflow: Full end-to-end process with rollback capability
- Preflight: System requirement validation and capability detection
- Logging: Structured JSON logging with security redaction
- Testing: 100+ tests with security, integration, and unit coverage
- Deployment: Automated staging deployment with CI/CD ready
- Complete Migration Workflow: Handshake → Files → Database → Finalize
- Robust Error Handling: Automatic retry and recovery mechanisms
- Security Hardening: Path traversal protection, input sanitization
- Performance Optimized: Efficient chunking and streaming
- WordPress Integration: Proper hooks, options, and standards compliance
The plugin follows WordPress best practices with a service-oriented architecture:

git clone https://github.com/vidarbrekke/wp-migrate.git
cd wp-migrate/wp-migrate
composer install- Copy
wp-migratetowp-content/plugins/ - Activate WP-Migrate: Production → Staging Migration
- Go to Settings → WP-Migrate
- Configure shared key and peer URL
# Test connectivity
curl -X POST https://your-site.com/wp-json/migrate/v1/handshake \
-H "X-MIG-Timestamp: $(date +%s)000" \
-H "X-MIG-Nonce: $(openssl rand -base64 16)" \
-H "X-MIG-Peer: https://staging-site.com" \
-H "X-MIG-Signature: [calculated-hmac]"- HMAC Authentication: All requests cryptographically signed
- TLS Enforcement: HTTPS required (with proxy header support)
- Nonce Protection: Replay attack prevention
- Input Validation: Comprehensive parameter sanitization
- Path Security: Directory traversal protection
- Handshake → Verify connectivity & run preflight checks
- Prepare → Set job state & configuration
- File Sync → Chunked uploads with resume capability
- Database → Export/import with URL rewriting
- Finalize → Cleanup & activation
