Migrations Generator Laravel Package

Product Decisions This Supports

• Brownfield adoption of Laravel. The core value is reverse-engineering an existing database into Laravel migration files, which directly de-risks "we have a 10-year-old schema and want to move to Laravel" decisions. This release removes the last blocker (DBAL 4 / Carbon 3 alignment) for teams standardizing on Laravel 12.
• Database replatforming (roadmap-level). Release notes explicitly call out MariaDB → PostgreSQL scenarios. That makes this a supporting tool for a roadmap item like "migrate off managed MariaDB onto PostgreSQL," where you need a repeatable, version-controlled representation of the schema before and after the cutover.
• Build vs. buy: buy (and here, take the free option). Writing your own schema introspection layer against Doctrine DBAL is undifferentiated work with a long tail of type-mapping edge cases. Adopting this package is the obvious call versus in-house tooling; the only real cost is a dev-dependency.
• Onboarding and documentation. Generated migrations double as executable schema documentation for new engineers and for architecture reviews.
• Test fixture generation. Quickly scaffolding schema for integration tests or local environments without production data.
• Dependency-health signal. The 12.0.2 fix tells you the maintainer is tracking the Laravel 12 / Carbon 3 / DBAL 4 ecosystem rather than pinning to stale constraints — relevant when scoring maintenance risk in a dependency review.

When to Consider This Package

Adopt when most of the following hold:

• You have a pre-existing database and are introducing Laravel, or migrating a legacy app onto it.
• You are planning a DB engine move and want a reviewable, diffable artifact of the schema.
• You need one-time or occasional schema-to-migration generation, not continuous two-way sync.
• You are on Laravel 12 (this release is the line that makes that viable) or an older supported line with a compatible DBAL.
• You want the database schema under version control as a baseline, after which Laravel migrations become the source of truth.

Look elsewhere or proceed with caution when:

• The project is greenfield and migrations are hand-authored from day one — the tool adds nothing.
• You expect the database to remain the source of truth indefinitely; generated migrations go stale and create drift between the DB and the migration history.
• The schema relies heavily on stored procedures, triggers, custom types, partitions, or vendor-specific extensions — expect incomplete fidelity and plan manual follow-up.
• You need bidirectional or continuous schema synchronization; this is a generator, not a sync engine.
• You cannot tolerate a dev-only dependency whose compatibility is coupled to Doctrine DBAL major versions — note the doctrine/dbal:^4.0 requirement on the 12.x line, which may conflict with other packages still on DBAL 3.

How to Pitch It (Stakeholders)

To executives: This is a free, open-source Laravel package that converts an existing database into version-controlled migration files. Its practical value is risk and cost reduction on two roadmap items: moving a legacy application onto Laravel, and changing database engines. The new 12.0.2 release resolves a dependency conflict that previously blocked Laravel 12 projects, so the tool is usable on our current stack with no licensing cost and no vendor commitment.

To engineering: migrations-generator 12.0.2 aligns the Laravel 12 line with doctrine/dbal:^4.0, resolving the Carbon 3 → carbon-doctrine-types:^3 → DBAL 4 chain that previously forced a DBAL 3 pin and caused an ecosystem mismatch. It handles both DBAL schema manager APIs (createSchemaManager() on DBAL 4, getSchemaManager() fallback for older implementations), ships a regression test for that selection logic, and documents the 12.x compatibility story. Practical guidance: install as a dev dependency, generate a baseline migration set, review the output (especially enum, JSON, and index handling), then treat Laravel migrations as the source of truth going forward. Known constraint: DBAL 4 requirement may collide with other packages still on DBAL 3 — verify with a dependency resolution dry run before merging.
