Application modernization consulting
We thoroughly investigate your legacy application code and infrastructure, mine requirements and provide detailed guidance on the improvements that can help you to derive max value from previous investments.
Legacy app migration to cloud
Depending on the application and business needs, ScienceSoft offers one of the three ways to the cloud – application re-hosting, application re-platforming or application rearchitecting.
Application reengineering
With a wide pool of legacy application modernization skills, we can help you restore and slightly modify code and design of your long-running enterprise applications.
Application recoding (automated and customized)
We revive your applications created on the basis of legacy languages and platforms (such as PowerBuilder, Delphi, VB, C++, COBOL) or aging technologies (outdated Java and .NET versions) with the use of modern programming languages, frameworks and databases.
Application containerization
Across all modernization options, we can pack your apps or their parts into packages isolated from each other at the OS level.

Advanced Technologies We Are Ready to Implement
The Financial Times Includes ScienceSoft USA Corporation in the List of the Americas’ Fastest-Growing Companies 2023
For the second year in a row, ScienceSoft USA Corporation ranks among 500 American companies with the highest revenue growth. This achievement is the result of our unfailing commitment to provide high-quality IT services and create best-value solutions that meet and even exceed our clients’ expectations.

The total cost of application modernization can range from $10,000–$15,000 for a UI upgrade or rehosting of a small app to $50,000–$250,000 for a substantial modernization of a medium/large app. If extensive re-engineering, deep recoding, or implementation of advanced techs (e.g., big data, AI/ML) is required, the cost may reach $500,000+ for a large application.
Among the key cost factors that influence the price of app modernization are:
- The complexity of applications and their dependencies.
- The volume of data to transfer.
- The life span of the application and its cloud migration readiness; the scope of infrastructure, code and configuration changes required.
- The extent of modernization automation and the cost of the relevant software licenses (e.g., code conversion tools).
- The required testing efforts.

When businesses come to us for legacy app modernization, we often recommend them to consider cloud migration as a part of the project. At this point, moving to the cloud is virtually always the most rational thing to do: you reduce the operational costs by up to 60%, achieve 99.9% app availability, and gain access to the cloud-dependent techs such as AI automation and data science. To make cloud migration fast and secure, ScienceSoft’s team divides legacy software into manageable parts and ensures gradual transition from one stable state to the next one. We also offer our clients to start off with a pilot migration: it helps assess the viability of the chosen migration approach and make the required tweaks cost-efficiently and risk-free.
