Does this skill support code-level migrations?

Yes, it includes strategies for feature flag implementation and the Strangler Fig pattern to migrate code from legacy systems to new implementations incrementally.

What safety checks are included in the workflow?

The skill provides comprehensive checklists covering mandatory backups, staging environment testing, data integrity validation, and long-term monitoring post-deployment.

How does the Migration Helper prevent downtime during database updates?

It guides you through multi-phase patterns such as adding nullable columns first, performing dual-writes, and batching data backfills before finalizing changes to ensure the database remains available to the application.

Can I use it with any database?

The guidance covers general SQL best practices and specific implementation patterns suitable for most relational databases like PostgreSQL and MySQL, including concurrent index creation.

Database Management

Facilitates safe database and code migrations using zero-downtime strategies and proven implementation patterns.

About

Migration Helper is a specialized capability within the Aura Frog plugin designed to mitigate the risks associated with database schema changes and significant code refactors. It provides AI-guided instructions for complex operations like renaming columns, adding indices concurrently, and executing multi-phase data backfills. By enforcing best practices such as the Strangler Fig pattern and dual-write strategies, it ensures that transitions remain reversible and do not interrupt service availability for production applications.

Key Features

Multi-tier rollback strategy guidance for varying failure scenarios.
Standardized migration script templates for TypeScript and SQL environments.
Zero-downtime database schema migration patterns including Dual-write and Add/Backfill/Drop phases.
Safe code migration strategies using Feature Flags and the Strangler Fig pattern.
1 GitHub stars
Comprehensive safety checklists for pre-migration, execution, and post-migration validation.

Use Cases

Safely adding required columns or concurrent indices to large-scale data tables.
Refactoring legacy monolith logic into modern microservices using incremental routing.
Transitioning a high-traffic production database schema without service interruption.
