Data Migration

Handle data and schema migrations safely.

Migration Checklist

Schema Migration

• Define forward and reverse schema migration scripts
• Verify schema changes are backward compatible where needed
• Check for data type changes that may cause truncation or loss
• Ensure index and constraint updates are included

Data Format Conversion

• Identify all serialization format changes
• Implement data transformation for existing records
• Verify date, time, and locale format compatibility
• Check for encoding changes affecting stored data

Configuration Migration

• Map old configuration keys to new equivalents
• Provide default values for newly required settings
• Validate migrated configuration against new schema
• Ensure environment-specific overrides are preserved

Data Integrity

• Verify referential integrity after migration
• Run checksums or row counts to confirm completeness
• Check for orphaned records or dangling references
• Validate business logic constraints on migrated data
