Legacy Application Modernization Services & Consulting

Evolve your systems to future-proof your business

Why legacy modernization is a must

Your legacy applications are not like fine wine—they don’t get better with age. Yet customer expectations and user needs are constantly evolving. Companies with strong legacy system modernization strategies will be much better positioned to flex to these changes, now and in the future.

Old systems with technical debt don’t play well with new systems, which can be a huge drag on new development. Legacy applications are also expensive to maintain: All that money you’ll spend keeping old software afloat could be much better spent on a modern, scalable software solution!

When it comes to legacy software modernization, time is truly of the essence. The pool of developers who can support your old system grows smaller each day, while speed-to-market becomes increasingly critical. In order to keep up with competitors and digital disruptors, you need to move faster on product and feature releases. Your legacy systems will keep your teams bound to workflows that slow your business processes and hinder your agility.

Where there’s the will, we can find the way! We’ve guided organizations of all types on their modernization journeys, providing top-notch application modernization services. It’s a complex road—we’ve seen companies start and stall for a number of avoidable reasons. So don’t go it alone! Even if you can’t see them now, the modernization pitfalls you’ll avert down the line are worth committing to a partner-in-evolution today.

So many IT organizations are still devoting anywhere from 60 to 80% of their time, energy, human resources and budget to supporting legacy systems rather than developing transformative solutions.

Legacy modernization drivers

If you’re exploring application modernization services, you’re probably feeling the burden that old systems are putting on your teams and your business. The reasons to change are everywhere and mounting: Once you recognize the signs you’ll realize why it’s so important to begin.


Consumerization of technology

The bar on experience is rising: Businesses must look at their own IT people as customers in order to operate efficiently. Intuitive user experiences and seamless integration are table stakes for both business users and consumers.

The data

The dramatic increase in available data necessitates new capabilities to deliver deeper insights. Legacy systems often give way scattered or inaccessible data—leading to uninformed decision-making and missed opportunities.

The growth

The competitive landscape is growing, with mounting pressure from disruptors. Software can be your differentiator. Transformation is critical to gain the competitive edge—and that evolution starts with legacy application modernization.



Legacy applications get more complex over time, which can be a real drag on your development. Old systems accumulate technical debt, which makes it difficult to add new features and integrate with new tech.


While you may balk at the cost of rewriting legacy applications, don’t forget that it gets expensive to maintain legacy systems over time—and that cost becomes less justifiable as technology around it evolves.


When the people who wrote your old code move on, that tribal knowledge goes with them. Legacy applications written in old languages may repel modern developers, and it’s inefficient to teach new dogs old tricks.

Benefits of legacy modernization services

It can feel intimidating to start down the path of rewriting your legacy applications, but the short and long term benefits certainly outweigh the upfront time and costs. And the sooner you start modernizing legacy systems, the sooner you begin to realize the benefits!

Assess the business

A thorough and thoughtful system modernization assessment mitigates risks often associated with business-critical IT efforts. We not only survey your old system, we look at the business capabilities of the organization and your team.

Set the boundaries

Isolating your modernization effort creates focus. By goal-setting, you’ll be able to identify the thing you want to change and hone the impact you want to make. We help you figure out what the most important elements are to change, weighing all factors.

Choose your starting point

Once you determine where to focus your efforts, now you’ll decide what to start on. We offer some expert advice on that decision which involves evaluating objective and subjective criteria and identifying the elements that are high value and low risk.

Launch your pilot

A pilot means building a small part of the big picture while putting modernized processes into play. We guide you through, from concept to deployment and testing, and focus on training, observation, and recalibration along the way.

Measure and manage

Once you have something in production, we can gather quantitative data based on your KPIs, then survey users for real-life feedback. Looking at these metrics together allows us to manage expectations going forward and effectively prevent scope creep.

Ongoing considerations

The learnings we gain at the start of your legacy modernization project will accelerate your efforts going forward. We make sure teams are open to change, and focus on continual improvement processes like: assessing the user groups, ongoing training, and diligent documentation.

Preparing for the next phase

Now, not only do we have hands-on learnings, we have tools for prioritization. Some tactics we employ to identify which feature to tackle next include: Turning “nice-to-haves” into the next thing, working on features close to the one completed, seeding plans from the start, or reassessing your goals and identifying new needs.

As you can see—rewriting legacy applications is an ongoing and iterative process, involving more than just your systems. That’s why it’s critical to have an experienced transformation partner to keep your team progressing smoothly in the right direction!
