Modernize Your Monolith. Without Rewriting Everything.

Full rewrites fail. Jardis generates the DDD target architecture for your PHP monolith, so you can migrate bounded context by bounded context while the system keeps running.

Why Modernization Projects Fail.

The monolith grows, the architecture erodes. But the big-bang rewrite is not the answer.

The rewrite that never ships

Teams start ambitiously with a full rewrite. 18 months later, two systems run in parallel, neither complete. Features get built twice, bugs get fixed twice.

No clear target architecture

Migration without a target architecture just produces a new monolith. Without defined domain boundaries, you move the same problems into a new repository.

Feature development grinds to a halt

During the rewrite, the team ships no new features. The business loses patience, the migration gets cancelled. The monolith stays.

How Jardis Solves Brownfield Migration.

Jardis defines the target architecture and generates the code. Your team migrates incrementally, without stopping operations.

DOMAIN BOUNDARIES

Target architecture from your domain model

You model your bounded contexts in Jardis. The builder generates the complete target architecture with clear package boundaries. Each context becomes a standalone module that can coexist alongside the monolith.

MIGRATION PATH

Context by context, not big bang

Start with the bounded context that causes the most pain. Jardis generates the target module, your team migrates the logic. The monolith shrinks with each step. Feature development continues in parallel.

PRODUCTION-READY

Production-ready structures from day one

Entities, aggregates, commands, events, repository interfaces: all generated, all architecture-compliant. No boilerplate writing, no debates about folder structures. The team focuses on migrating business logic.

Why Teams Migrate with Jardis.

Because incremental migration only works when the target architecture is defined.

> Coexistence

Old and New Run Side by Side

Each generated bounded context is a standalone package. It can be deployed alongside the monolith while you migrate logic piece by piece.

> Velocity

Ship Features During the Migration

No feature freeze. New features are built directly in the new bounded context. Legacy features migrate at your own pace.

> Consistency

Same Architecture in Every Context

Whether team A or team B migrates: the generated code follows the same patterns. No architecture drift, no team-specific deviations.

Frequently Asked Questions

Answers about brownfield migration with Jardis.

No. That is exactly the point. You pick one bounded context, generate the target structure with Jardis, and migrate the business logic. The rest of the monolith continues running unchanged.
