  • Enables integration with modern systems, driving business agility and future growth.

Businesses that invest in legacy application migration today will gain a competitive advantage for tomorrow.

What We Offer

Services Tailored to Your Vision

In the pursuit of your strategic goals, we assess the system weaknesses and craft a business-aligned legacy application migration strategy. Like a surgery, it requires precision and expert execution to ensure a healthy application and data migration without downtimes and data losses.

  • Application Rehosting

    Want to avoid the rising maintenance costs of a legacy provider without a complete app overhaul? Orchestrate migrations to a new infrastructure without changing the current code or architecture. Within our legacy application migration strategy, we provide:

    • Business analysis of a current infrastructure,
    • Assessment and choice of vendors,
    • Crafting a comprehensive migration strategy (moving legacy applications to cloud, data centers, etc.),
    • The process roadmaps, pointing out crucial cornerstones,
    • A “lift and shift” transition to a new infrastructure with post-migration support.

    Save your resources and boost cost efficiency for countless business opportunities.

  • Application Replatforming

    Need to improve your app’s scalability and performance quickly and easily? We fine-tune and adapt applications for a modern platform, balancing efforts and benefits, to ultimately optimize performance. A legacy system migration strategy encompasses:

    • Analysis of the current environment, unveiling hidden dependencies and limitations,
    • Creating an appropriate legacy application migration strategy (migration of on-premise server to the cloud, turning to containerization with Docker, etc.),
    • Selection of a target platform or provider,
    • Minor codebase refinement to reduce operational costs and improve performance,
    • Ongoing post-replatforming support.

    With timely enhancements, your app will be future-proof and efficient without complete rewriting and replacement.

  • Application Refactoring

    Need targeted improvements without changing the logic of how your app works? We rewrite and restructure parts of your application, keeping core functionalities untouched. All this is to boost performance, scalability, and throughput. We provide:

    • Codebase analysis,
    • Creating a legacy system migration strategy (e.g., modular restructuring, incremental refactoring, branch-based refactoring, etc.),
    • Creation of unit tests,
    • Refactoring process, including removing redundancies, renaming for clarity, etc.),
    • Running tests,
    • Preparing detailed documentation and handoff.

    Upgrade the core functionality of your app, ensuring business continuity and improved performance.

Our process

How We Work

A proven, structured process turns complex migrations into seamless transformations, minimizing risks to the maximum impact.

01.

01. Analysis & Planning

Every successful migration starts with a deep understanding of initial restrictions. We assess architecture, dependencies, performance metrics — all that hide potential weaknesses. Then, depending on your goals, we forge a step-by-step application migration blueprint to keep your project on track.

02.

02. Roadmapping & Routing

Furthermore, our team evaluates cloud service providers like AWS, Azure, and Google Cloud, considering pricing, scalability, security, and service depth. We match your application’s needs with the right services for every layer, from computing and storage to databases and networking, for a stable, scalable foundation.

03.

03. Code & Data Transfer

We modernize your applications with the best-fit strategy: refactoring, rehosting, or replatforming. We rewrite the codebase to enhance performance, or we lift-and-shift apps for a fast, cost-effective migration with minimal disruption.

04.

04. Validation & Optimization

Thorough testing ensures that everything functions as expected after the legacy application migration. Additionally, we measure key metrics such as response time, throughput, and scalability to maximize performance.

05.

05. Deployment & Maintenance

Once testing is complete, we deploy your app to the production environment under our continuous oversight, ensuring a smooth, risk-free transition. Additionally, your app will be continuously monitored and optimized until a stable, uninterrupted performance is guaranteed, no matter the conditions.

FAQ

Frequently Asked Questions

  • What are the business risks of not modernizing our legacy applications?

    The problems start silently but then snowball. A total overhaul becomes necessary instead of minor changes. Security threats, downtimes, and higher maintenance costs are just a few of the problems associated with legacy tech.

  • What are the potential risks of modernization, and how can we mitigate them?

    Sometimes, legacy app migration is difficult to settle on, as it brings many challenges, including downtimes, data losses, app compatibility, and budget concerns. However, a good legacy system migration strategy reduces risks thanks to careful planning, phased work, backups, and pilot tests.

  • Should we adopt a phased migration approach or migrate all at once?

    The decision depends on your risk tolerance, system complexity, and business requirements. After a thorough assessment, we’ll help you choose the right legacy migration strategy.

  • How long can each application tolerate downtime during the migration?

    Some systems, like internal corporate tools, tolerate downtime well. While others like banking apps can’t be switched off even for an hour. That’s why we analyze dependencies and business priorities to tailor a migration process that minimizes disruption.

  • Who is responsible for each part of the migration project?

    Our team collaborates closely with your IT and business teams. We handle technical execution, while you oversee business alignment and approvals.

  • What is legacy application?

    A legacy application is outdated software in use. Businesses rely on legacy systems because they fundamentally need their apps for operations, even though these apps are hard and risky to maintain.
