01
Stabilize and upgrade
Bring unsupported runtimes and frameworks to supported versions, remove critical vulnerabilities, add tests, and make deployment repeatable before larger change.
Lower immediate risk and a clearer baseline
Legacy Application Modernization
Keep the business logic.
Lose the technical drag.
A legacy application may still run the business while slowing every change. AIONDATA helps you understand it, stabilize it, and move it toward a maintainable architecture—incrementally when possible, with a controlled replacement when necessary.

THE RIGHT MOVE FOR EACH WORKLOAD
Modernize with a reason.
Not for a trend.
We assess business risk, dependencies, operating cost, security, performance and team capability before choosing a target architecture.
02
Modularize the monolith
Create boundaries around business domains, extract high-change functions, and route traffic between old and new components while both remain observable.
Change one area without rewriting everything
03
Replatform or rebuild
Move selected capabilities to Node.js, TypeScript, modern PHP, managed runtimes, containers or serverless where the business case supports it.

Modernize data and interfaces
Untangle shared schemas, introduce versioned APIs and events, migrate data in rehearsed waves, and reconcile records before final cutover.
Reliable data with explicit ownership
PRACTICAL MODERNIZATION PATHS
What a migration can
actually look like.
These are architecture patterns, not automatic recommendations. The right answer may be to retain, update or retire a workload rather than rewrite it.
Legacy PHPModern PHP / Laravel
Upgrade the runtime and framework when the core application is sound and the team benefits more from lower risk than a language change.
Best when dependencies can be upgraded and the architecture can be improved without a full rewrite.PHP monolithNode.js / TypeScript services
Extract a high-change domain behind an API, route only that workflow to the new service, and keep the remaining application operational.
Use a staged strangler pattern; a language rewrite alone does not fix unclear domains or data ownership.Server-rendered UIModern web experience
Separate the presentation layer where user experience and release cadence justify it, while preserving proven business rules behind stable interfaces.
Accessibility, SEO, authentication and feature parity belong in acceptance criteria—not after launch.Shared databaseOwned data boundaries
Introduce service-owned access and a governed migration path before decomposing tables that many workflows still depend on.
Dual writes and data copies need reconciliation, observability and a defined end date.MOVE WITHOUT LOSING CONTROL
A safer cutover.
A system your team can run.
Migration is complete only when traffic, data, monitoring, recovery and ownership work in the new environment.
Business continuity by design
Feature parity, rollback points, parallel operation and cutover windows are agreed before production traffic moves.
Security improves during the move
Secrets, identity, dependencies, data access and audit needs become part of the target—not a later cleanup project.
Operability ships with the code
Build pipelines, environments, logging, alerts, recovery steps and ownership are delivered alongside the modernized application.

STRAIGHT ANSWERS
Questions to settle
before you migrate.
We use current vendor guidance as an input, then validate the design against your workload and constraints.
Should we rewrite our legacy PHP application in Node.js?
Not automatically. If the PHP application is structurally sound, upgrading to a supported PHP version and modern framework may be faster and safer. Node.js or TypeScript can make sense for selected services, shared team skills, real-time workloads or a new product boundary. We compare both paths before recommending one.
Can you modernize the application without a long shutdown?
Often, yes. We can place stable interfaces or routing in front of the existing application, move bounded capabilities in stages, synchronize data where necessary, and cut traffic over gradually. The feasible downtime and rollback design depend on the application and its data model.
What do you assess before estimating a migration?
We review business-critical journeys, source code, framework and runtime versions, third-party packages, database dependencies, scheduled jobs, integrations, authentication, deployment, observability, test coverage and operational constraints. A reliable estimate needs both technical and business context.
Do you only migrate PHP applications?
No. PHP is a common starting point, but the same assessment and staged modernization approach applies to older Java, .NET, Node.js, Python, database-heavy web applications and custom internal systems.
Who owns the modernized code and documentation?
Ownership, repositories and licensing are agreed in the project scope. Our standard delivery approach includes source code, architecture decisions, deployment material, operational runbooks and a technical handover for the work we deliver.
