Migration Classes vs Raw SQL Dump for Schema Consistency in Contao Docker Environments

The goal is to guarantee that every developer, CI agent, and staging server starts with an identical Contao database schema when using a repeatable Docker‑based workflow.

The concrete constraint is choosing between two documented approaches: running Contao’s migration classes (contao‑migrate) inside the container or importing a raw SQL dump from production. Each method influences schema drift, rollback capability, and isolation testing differently, but the trade‑off is not clearly prescribed for a given team size or release frequency.

Which approach provides stronger assurance that the schema matches the versioned codebase when onboarding new contributors?
How does each method affect the ability to verify and test migration rollback steps in an isolated container?
What are the implications for CI/CD pipeline reliability when relying on one strategy over the other?
