Application Modernization

Systems that handle vital business processes are hard to replace, but keeping legacy applications running smoothly while meeting day-to-day needs can be a time-consuming and resource-intensive affair.

Why should you modernize your legacy applications?

Modernization is about taking the DNA, of the original software, and modernizing it to better serve organizational needs. Application modernization boosts innovation because it allows the company to focus on new ideas, processes, and workflows.

Legacy applications are often monolithic, making them difficult to support, update, scale, or access using mobile devices. They can also lead to inaccessible data silos, weakening your decision-making process and cutting you off from valuable data insights. Taking advantage of new cloud technologies helps your organization stay competitive in the marketplace.

Key Benefits of Application Modernization

Most businesses have significant financial and operational investments in their application portfolio. Modernization is an opportunity to increase the benefit of your existing solutions, by leveraging innovation in the cloud. It also leads to rethinking, updating, and improving business processes.

ThreeWill’s application modernization strategy will help your organization increase the speed, scalability, and stability of your business operations. This reduces the resources and costs needed to run an application while delivering new business value. Taking your legacy applications to a whole new level allows your company to take advantage of new, innovative technologies.

The Modernization Journey

Modernization keeps your applications relevant, ensuring they can keep up with users’ needs. An Application Modernization Discovery, Assessment, and Planning effort is the first step in modernizing your legacy applications.


There are a number of options for modernizing your application portfolio, and this helps to assess the overall scope and complexity of your digital estate and to provide an overall modernization roadmap.

Options for each application include:


  • Leave as-is: Also known as “lift and shift,” this process moves your existing application from a legacy environment to new, modern infrastructure (such as a cloud platform). Little to no changes are made to the application’s underlying architecture or code.
  • Modernize: This approach essentially restructures the legacy application so it runs efficiently in a new environment. Legacy systems are often modernized incrementally to reduce operational risk. Modernizing includes restructuring the existing code base and rewriting code.
  • Replace or retire: Business applications sometimes outlive their value to the organization, especially when their functionality is duplicated by other solutions. Retirement removes legacy applications from use but retains access to the application’s data. Legacy data can be stored while mission-critical information is migrated to the new application.

No two organizations have the same application portfolios, so there is no one-size-fits-all roadmap for modernization. ThreeWill works with your organization to review existing requirements and identify the most critical needs. Take the first step to a successful migration journey.

  • “We worked with ThreeWill on a Jive - Microsoft 365 migration for a multinational client. The migration involved multiple territories and languages and considerable complexity. ThreeWill demonstrated exceptional rigor in their process, whilst using agile to respond to constant challenges that emerged at various points during the evolution of the project. Their clear communication with the client about their process, progress, and options meant that there was always alignment between them and the client and no surprises. When they were asked to come up with options for meeting particular challenges, they had a transparent and consistent methodology which meant the client could make informed decisions. The technology solution itself resulted in an exceptionally high-quality outcome, delivered on time and within budget.”

  • “ThreeWill helped us extend Trove to meet our customer's needs. They helped us avoid costs for an existing subscription by connecting up Salesforce with SharePoint. Working with Eric was great - I appreciated the status updates and the burndown chart for understanding our budget. I also enjoyed the weekly meetings to update me on the status of the project. I was able to save tens of thousands of dollars a year because of this project.”

  • “ThreeWill helped us migrate from Jive to SharePoint. We were impressed with the methodology followed in the project. Standups and weekly reports were great communication. It was a particularly well-managed project - we had a highly committed team that met tight deadlines to make a year-end deadline. The project was under budget, and we were able to avoid an annual renewal fee that easily justified the project.”
