Legacy System Modernization Services

Legacy systems are often a nightmare scenario for integrating your business with cloud computing services, complying with modern security standards, and innovating your operations with cutting-edge technologies, including AI and machine learning. As well, legacy systems run on heavily outdated software which could be both a security risk and downfall your company performance. Legacy code often does not work with modern APIs making it not possible to connect the application with external services. In the course of time it becomes harder to find specialists ready to maintain continuous support of legacy applications.

Many decision-makers have a well-established opinion that modernization in this context leads to the loss of existing business logic and product functionality. However, in practice, a legacy system modernization implies updating existing components and rewriting legacy code into a modern stack, while preserving the existing product logic and functionality. Modernizing-a-legacy-system-as-a-service assumes a deep understanding of business operations of the company and the role of the system in them. So let’s discuss how full-cycle modernization of legacy systems is made and how to rebuild an outdated custom software solution into a modern system that performs as expected and meets your business goals.

Modernization of legacy systems: case studies

Let’s find out how our legacy systems modernization company solves the problems faced by clients with outdated software.


123Signup launched a SaaS solution for event and association management nearly 20 years ago. In 2015, the company decided to start cooperation with Integrio, as their cooperation with another software company was no longer productive.

The main task that was given to the Integrio team was to refactor the code and update legacy components in order to introduce new functionality into the existing product and to ensure better stability.

After in-depth analysis, the Integrio team identified existing shortcomings, developed a new user interface and several new blocks for end-to-end automation (for event and membership management, for donations, for reporting and analytics, for website creation, etc.), and integrated billing, POS, and some third party services.


As a result, 123Signup got the rebuilt version of their SaaS solution with improved functionality and interface. The collaboration between 123Signup and Integrio Systems continues to this day.

Tech stack:

  • Java
  • Oracle
  • Spring
  • Bootstrap
  • Hibernate
