Monitor your App Development in Real-Time

You don't have to wait for the UAT and scheduled status to know the status of your application development. Stepfinity has a fully transparent app development procedure where you can monitor the entire life-cycle of the application in real time. You can track the progress of all the modules of the application, monitor active sprint progress and preview upcoming milestones to ensure that your app development is on track. We coordinate with your team from day one to avoid technical or goal-oriented friction, which eliminates the ambiguity in development and ensures seamless delivery and deployment of the application.

Why Modernize

The Old System is Perishing Your Business

Nothing falls suddenly; neither will your business, but there will be signs, high maintenance costs, low performance, security threats. If you can relate, then this is the sign for you to modernize your business application.

Deploy Features Faster

Modern architecture gives you the ability to integrate with new features just in days, rather than months of fighting with the ancient code.

Advanced Security Systems

With evolving technology, security needs to be advanced tech to ensure the safety of confidential information.

Low maintenance cost

Old systems are brittle, you try to fix one place it breaks in another, increasing the maintenance cost, unlike modern applications.

Low Technical Debts

An old application has accumulated a lot of technical debts, which impacts the application's performance and, in the end, your business.

Liberty to Scale

The legacy system can support limited traffic before the performance starts impacting, but cloud-native applications can be adjusted with traffic size in real-time.

Core Capabilities

Modernization services built for the enterprise

Retire legacy risk in stages — from re-platforming to full architectural overhaul.

Application Layer

Re-Platforming Application

Transform the slow and overused application into a modern, high-performing one with the power of low-code and advanced agentic AI technology.

01
Data Layer

Cloud-Native Database

Migrate the legacy database into the cloud-base data with zero data loss through bootstrapping.

02
Integration Layer

STEP 02 BLUEPRINT

Strategizing

Restructuring the database, altering the architecture, re-platforming the application if required to attain the business goal.

STEP 03 EXECUTION

Development

Migrating the code, database or features module-wise into the cloud-native infrastructure.

STEP 04 PARALLEL RUN

Validation

Running the modernized application alongside the legacy application to ensure the same result before replacing it.

STEP 05 PRODUCTION

Replace & Optimize

Replace the legacy system with a modern eco-system with advanced features, high performance and zero technical debt.

THE TRANSFORMATION

Compare Together, See the Difference

The same business, running on two very different foundations.

LEGACY SYSTEM

Before Modernization

  • Very slow deployment and large downtime window
  • Business logic locked in old code
  • Non-responsive interface
  • Security gaps and vulnerabilities
  • Security gaps and vulnerabilities
Modern OutSystems Application

After Modernization

  • One-click deployment and minute of downtime
  • Preserved and full documented business logic
  • Fully responsive interface for any device
  • Tight security with cloud platform
  • Modular architecture for better dependency management

During the migration of the database, the records aren't altered in the source systems, and there is a full rollback plan on standby for any mishap.

QUESTIONS

What enterprise teams usually ask us

What is a key characteristic of a legacy system?

A key characteristic of a legacy system is that it is dependent on the outdates technologies for their most essential features or workflow, these outdates technologies is very important of the legacy system but they lack flexibility, scalability and compatibility due to which modifying or integrating them with modern application becomes a challenge for developer, due to which it slows down the modernization process and makes it costly as well.

What are common challenges in legacy system modernization?

The most common challenges developers face during modernizing the legacy systems include integration complexity, security risk, limited vendor support and the threat of business process interruption during the time of migration or re-platforming. The organization needs to maintain a balance during the transformation of the application with ongoing operations, budget constraints and regulatory requirements.

How can I automate legacy modernization?

Automation can prove to be a good way to accelerate legacy modernization speed by using AI- assisted development, reusable components, and automated testing and deployment pipelines. Modern platforms let teams wrap, extend and modernize the legacy applications while also ensuring to reduce the manual efforts and operational risk.

What is a legacy application?

A legacy application is an old software application that is built on outdated technology or architecture that we will use to support business operations. While the legacy application is very stable, but it's performance is questionable at best, with all the technical debt accumulated over the years and in addition to that, they are also extremely difficult to scale, integrate or update, which restricts the innovation and agility of the organization.
