Modernizing legacy applications has become a strategic priority for organizations preparing for AI-driven innovation. However, many organizations hesitate when figuring out how to begin before committing significant resources to changing decades-old systems they may not fully understand.

This is where the AWS Migration Acceleration Program (MAP) can help. MAP reduces both financial and technical barriers. When working with a Migration and Modernization Competency Partner, it provides funding and guidance to assess, mobilize and modernize with greater confidence. And, for organizations considering a ReDuX pilot, MAP provides a way to get started with a focused assessment before committing to a larger modernization effort.

What is AWS MAP?

AWS MAP is a comprehensive cloud migration program that combines proven methodologies, technical guidance, AWS expertise, and funding support to help organizations accelerate modernization initiatives. Rather than expecting organizations to move directly into implementation, MAP follows a phased approach that helps teams understand their environment, build a migration strategy, and execute modernization with reduced risk.

The program is structured around three phases:

  • Assess – Evaluate existing applications, understand dependencies, identify business value, and determine the best modernization approach.
  • Mobilize – Build the migration foundation, establish processes, prepare teams, and validate the modernization strategy.
  • Migrate & Modernize – Execute migration activities and modernize applications using AWS services and best practices.

For many organizations, the most valuable part of MAP is that funding is available even during the early assessment stage, before major modernization work begins. MAP funding is available through AWS Partners, including Karsun, that have achieved the AWS Migration and Modernization Competency. 

Why the Assessment Phase Matters

One of the biggest obstacles to modernization is uncertainty. Legacy applications often contain decades of undocumented business logic and institutional knowledge that exists primarily within the code itself. Organizations are understandably reluctant to invest in a large modernization effort without first understanding what they are working with. MAP helps remove that uncertainty.

Through assessment funding, organizations can gain visibility into their applications before making larger investment decisions. Instead of relying on assumptions, teams can evaluate complexity, identify risks, and build a roadmap based on real insights.

This allows decision-makers to answer critical questions such as:

  • What business rules exist inside the application?
  • Which systems are tightly coupled?
  • What should be modernized, retained, consolidated, or retired?
  • What level of effort should be expected?

Having these answers upfront leads to better planning and significantly reduces modernization risk.

Lowering the Barrier to Getting Started

Since MAP provides funding during the assessment phase, organizations do not have to begin with a large modernization commitment. Instead, they can start with a focused engagement that helps them understand their environment and determine the right path forward.

This approach is especially valuable for organizations considering large-scale legacy transformation. Rather than committing to a full migration immediately, they can validate assumptions, reduce uncertainty, and build executive confidence before moving into implementation. 

How Karsun Helps Organizations Maximize MAP

Karsun helps organizations take full advantage of MAP while accelerating modernization with AI-powered insights. 

Our AI-powered ReDuX platform naturally aligns with the MAP framework. During the Assess phase, ReDuX creates a comprehensive blueprint of legacy systems by analyzing source code, business logic, application dependencies, APIs, and data relationships. Instead of relying on assumptions, organizations gain a living understanding of how their applications actually operate. This foundation allows teams to make informed modernization decisions before writing new code or beginning migration efforts.

From there, ReDuX supports modernization throughout the remaining MAP journey by helping teams:

  • Discover and document legacy systems
  • Preserve critical business logic
  • Accelerate modernization with AI-assisted workflows
  • Reduce delivery risk through human-in-the-loop governance

The result is a modernization process that is both more informed and more predictable.

Start with Knowledge, Not Guesswork

Modernization does not have to begin with a leap of faith. With AWS MAP funding, organizations can start by understanding their legacy applications, identifying modernization opportunities, and building a roadmap based on evidence rather than assumptions. By combining AWS’s proven migration framework with Karsun’s AI-powered modernization capabilities, organizations can reduce risk, accelerate decision-making, and move toward modernization with greater confidence. Sometimes the most important step is not migration itself but rather, gaining the clarity to know what comes next.
