Migration Best Practices

This guide provides essential best practices and tips to ensure successful migration of your applications and databases to Elestio.

🎯 Pre-Migration Planning​

1. Inventory and Assessment​

  • Document Current Setup: Create a comprehensive inventory of your current infrastructure
  • Identify Dependencies: Map out all application dependencies, databases, and integrations
  • Check Compatibility: Verify that your applications are supported by Elestio
  • Version Matching: Ensure you use the same software versions to prevent compatibility issues

2. Risk Assessment​

  • Downtime Planning: Estimate and plan for acceptable downtime windows
  • Rollback Strategy: Prepare a detailed rollback plan in case migration fails
  • Impact Analysis: Identify critical business processes that might be affected
  • Communication Plan: Inform stakeholders about migration timeline and potential impacts

3. Resource Planning​

  • Storage Requirements: Calculate storage needs for both source data and migration process
  • Bandwidth Considerations: Plan for data transfer bandwidth requirements
  • Timeline Estimation: Create realistic timelines including buffer for unexpected issues
  • Team Coordination: Assign clear roles and responsibilities to team members

📋 Pre-Migration Checklist​

Data Preparation​

  • Complete Backup: Create full backups of all critical data and configurations
  • Test Backups: Verify backup integrity and restoration procedures
  • Data Cleanup: Remove unnecessary data to reduce migration time
  • Document Configurations: Record all custom configurations and settings

Environment Setup​

  • Elestio Account: Set up and verify your Elestio account
  • Access Credentials: Gather all necessary usernames, passwords, and API keys
  • Network Planning: Plan network configurations and firewall rules
  • SSL Certificates: Prepare SSL certificates if using custom domains

Testing Environment​

  • Staging Environment: Set up a staging environment for testing
  • Test Migration: Perform a trial migration with a subset of data
  • Validation Procedures: Define success criteria and validation steps
  • Performance Benchmarks: Establish baseline performance metrics

🔄 Migration Process Best Practices​

1. Incremental Migration​

  • Phased Approach: Migrate in phases rather than all at once
  • Start Small: Begin with less critical applications or datasets
  • Progressive Validation: Validate each phase before proceeding to the next
  • Learn and Adapt: Use early phases to refine your migration process

2. Data Migration​

  • Consistent State: Ensure data is in a consistent state before migration
  • Checksum Verification: Use checksums to verify data integrity
  • Transaction Logs: Maintain transaction logs for database migrations
  • Parallel Processing: Use parallel processing where possible to reduce migration time

3. Application Migration​

  • Configuration Management: Use configuration management tools where possible
  • Environment Variables: Document and migrate all environment variables
  • Service Dependencies: Migrate dependencies in the correct order
  • Connection Strings: Update all connection strings and endpoints

✅ Testing and Validation​

1. Functional Testing​

  • Feature Verification: Test all application features and functionalities
  • User Acceptance: Conduct user acceptance testing with key stakeholders
  • Integration Testing: Verify all integrations work correctly
  • Performance Testing: Compare performance against baseline metrics

2. Data Validation​

  • Data Integrity: Verify all data has been migrated correctly
  • Record Counts: Compare record counts between source and destination
  • Data Relationships: Ensure all relationships and constraints are intact
  • Data Quality: Check for any data corruption or loss

3. Security Validation​

  • Access Controls: Verify all access controls and permissions
  • Encryption: Ensure data encryption is properly configured
  • Compliance: Validate compliance with relevant regulations
  • Vulnerability Scanning: Perform security scans on the new environment

🚨 Common Pitfalls and How to Avoid Them​

1. Version Mismatches​

  • Problem: Different software versions causing compatibility issues
  • Solution: Always match versions between source and destination
  • Prevention: Document all version numbers before starting migration

2. Incomplete Data Migration​

  • Problem: Missing data due to incomplete export/import processes
  • Solution: Use checksums and record counts for validation
  • Prevention: Test migration process thoroughly in staging environment

3. Configuration Drift​

  • Problem: Missing or incorrect configurations in the new environment
  • Solution: Document all configurations and use automation where possible
  • Prevention: Create configuration checklists and validation procedures

4. Performance Degradation​

  • Problem: New environment performs worse than expected
  • Solution: Monitor performance metrics and optimize as needed
  • Prevention: Establish performance baselines and conduct load testing

🔧 Troubleshooting Guidelines​

1. Migration Failures​

# Check container logs
docker logs <container_name>

# Restart services
docker-compose down
docker-compose up -d --build

# Check system resources
df -h  # Disk space
free -m  # Memory usage
top  # CPU usage

2. Database Issues​

  • Connection Problems: Verify connection strings and credentials
  • Performance Issues: Check indexes and query optimization
  • Data Corruption: Restore from backup and retry migration
  • Lock Timeouts: Adjust timeout settings and retry during off-peak hours

3. Application Issues​

  • Dependency Problems: Verify all dependencies are properly installed
  • Configuration Errors: Double-check all configuration files
  • Permission Issues: Ensure proper file and directory permissions
  • Resource Constraints: Monitor and adjust resource allocations
