Modernization of Legacy System Generates Efficiency and Security for the Pharmaceutical Industry

Pharmaceutical company reestablished the use of the new drug control system with a modernization project that delivered efficiency, functionality, stability, and security


With its proprietary system focused on new drug control, a global pharmaceutical company faced the challenge of updating the platform due to technological obsolescence.


The act digital team updated the legacy system, a project that included migrating to newer technology, adding features compatible with current market demands, and fixing issues with existing resources.


The modernization of the legacy system proved to be the most efficient solution to meet the pharmaceutical company’s needs, ensuring the continuity of its use and preserving the rich database maintained on the platform. The system showed increased efficiency and is now prepared for further improvements and updates.

In recent years, the pharmaceutical industry has faced significant challenges globally, driven by rapid technological evolution and increasing demands for innovation. Research and development in this sector increasingly rely on the security of generating and storing information, leading many control systems to be created and managed by internal teams.

In this context, the modernization of legacy systems becomes an essential strategy to ensure the sustainability and competitiveness of these companies. This challenge was faced by a major global pharmaceutical company, a leader in its segment. The organization developed its own system for controlling new drugs seven years ago, adopting technology that is gradually being discontinued.

During this period, the legacy system was not improved, failing to make important changes to ensure its continuity. The act digital team was hired to perform this task, leading the update project and recognizing the need to align operations with contemporary sector demands.

Modernization addressed the challenges of technological obsolescence, aiming to optimize operational efficiency, enhance functionalities, ensure operational stability, and, above all, strengthen the security of data and processes involved.


Client: global pharmaceutical leader in biotechnology

Dedicated to offering medications with innovative biotechnology, the pharmaceutical industry that hired act digital to update its legacy system operates globally and is a leader in the market. The increasing competitiveness in the industry, which increasingly adopts new technologies and scientific advancements, demands continuous adaptation to technology and, essentially, attention to data security, especially regarding innovations in new substances.

In this context, the company relies on an internal team for developing its own systems. This care reflects the importance of industrial secrecy and demonstrates the constant challenge of technological updates, covering both the core business of the company and modernization in the Information Technology area.

Challenge: Modernization of Legacy System for Innovation Process Control

For seven years, the pharmaceutical company has relied on an internally created legacy system for controlling new drugs, resulting in a fundamental database for the area. Despite its relevance, the platform, which was aligned with the company’s innovation processes, became obsolete over time and was falling out of use.

In this scenario, creating a new platform or buying a tool to replace the legacy system presented high financial and operational costs. One of the associated risks was the potential loss of data and processes related to research on new substances.

Before resorting to this option, the company sought to update the legacy system, a project led and conducted by act digital. The update process (Tech Stack Upgrade) focused on addressing problems caused by instabilities and the lack of improvements over the years.

The technology used in creating the system was being discontinued, requiring a transition to newer versions. The legacy system was originally developed using AngularJS technology, and it was necessary to migrate to Angular 2+. Additionally, functionalities that needed to be incorporated and others that required correction were identified throughout the project.

Solution: Modernization of Legacy System with Technological Migration

Faced with the challenges presented, the act digital team worked on analyzing the problems to propose solutions compatible with the scenario.


The methodology employed throughout the project included stages such as:

  • Mapping of problems and areas for improvement.
  • Conducting unit and end-to-end tests.
  • Refactoring some of the existing components that were in AngularJS.
  • Migrating from AngularJS technology to Angular 2+ (above version 12).
  • Incorporating new functionalities related to the segment’s new challenges.

Applied Technologies

The technologies applied to the legacy system’s update include:

  • Angular 2+
  • Node.js

Results: Stabilization, Security, and Performance

The modernization of the legacy system allowed the continued use of the platform, which now exhibits more stable, functional, and efficient performance.

Among the results observed after the update are:

- Agility in Creating Formulations: Users now have access to data that can be used more simply and quickly. For example, transporting information from one spreadsheet to another for an entire series of data, something that was previously only possible pointwise (one piece of information at a time). This resulted in a 50% gain in agility.

- Increased Confidence in Use: The platform was falling out of use due to difficulties, and today, users prefer to use the legacy system.

- Higher Level of Protection and Security: After the update of the legacy system, no security incidents were reported or detected.

- Improved Performance: After the update, the legacy system showed a performance gain of about 30%, a percentage that will be even higher with server updates and other mechanisms linked to the platform.

- Bug Resolution: Over 40% increase in bug and failure resolution due to the greater stability and agility of the legacy system.
