Cascade Created Conflicting Database Migrations
Database migrations generated by Cascade conflict with existing migrations, causing the migration engine to fail during startup. The application won't boot because Flyway/Liquibase can't determine the correct migration order.
Cascade may have generated new migrations without checking existing schema version files.
Error Messages You Might See
Migration validation failed
Duplicate migration version
Migration V2__*.sql conflicts with V2__*.sql
Flyway: Unable to determine latest schema version
Common Causes
- Cascade generated V2__*.sql migration with same timestamp as existing migration
- Cascade created backward-incompatible schema changes without intermediate migrations
- Migration naming convention not followed (version ordering incorrect)
- Cascade added DROP TABLE statements that conflict with dependent tables
How to Fix It
Check migrations directory for duplicate version numbers. Review Cascade's generated migration for compatibility with existing schema. If conflicts, rename Cascade migration with higher version number. Test migration on copy of production database before deploying.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

How do I view applied migrations?
Query flyway_schema_history table: SELECT * FROM flyway_schema_history ORDER BY installed_rank;
Can I fix migration conflicts?
Rename Cascade's migration to higher version (e.g., V4__* instead of V2__*) and reorder appropriately.
