Frequently Asked Questions

What does Legacy Application Modernization mean?

Legacy Application Modernization means upgrading your old systems so they work faster, safer, and more efficiently. It usually involves moving your applications and data to the cloud, rebuilding slow parts into faster microservices, updating the interface so it’s modern and user-friendly, and adding secure APIs so everything connects seamlessly. By modernizing, you get a system that’s easier to maintain, more secure, cost-effective, and ready to scale with your business, all without disrupting your day-to-day operations.

Why should your business consider Legacy Application Modernization?

If outdated software is slowing you down, modernization is the solution. It helps cut downtime, reduce high maintenance costs, and lets you release new features quickly. It also improves security and compliance, while giving your team and investors confidence that your technology can scale with your business goals.

How long does a Legacy Application Modernization project usually take?

The timeframe depends on your system’s size and complexity. Some projects can be completed in weeks, while larger transformations may take a few months. We follow a sprint-based approach, so you see progress at every stage with clear updates on what’s done and what’s coming next. Throughout the process, we stay connected with you using communication channels like Slack and Google Meet, and we manage the work transparently through Jira sprints. Whenever you need to review reports, ask questions, or assign tasks, our team is always active and available to respond quickly.

Will Legacy Application Modernization affect your day-to-day operations?

We make sure your daily work isn’t disturbed while upgrades happen. We migrate it carefully using proven tools and backups at every step. Most updates are carried out in parallel environments or during off-hours. Using strategies like feature flags and staged releases, we keep the process smooth so your team and customers hardly notice the transition.

We work with leading technologies like AWS, Azure, and GCP for cloud platforms, modern UI/UX frameworks for better usability, microservices for flexibility, and secure APIs for integration.

Is modernization only for big enterprises or does it make sense for small businesses too?

It absolutely makes sense for small and mid-sized businesses. In fact, startups and growing companies benefit the most because they avoid scaling pains early. Modernization makes your systems flexible, so you don’t face major roadblocks later.
