How Edvantis Modernized Legacy Codebase for a Major German Telecom Provider

The Freenet Group is a leading telecom network provider in Germany, serving 8.3 million customers through its four major brands. The company contacted Edvantis when its original systems, based on Java 6 and JBoss (WildFly) application servers, no longer matched its evolving needs. 

Edvantis assembled a team familiar with the Spring Boot framework, Java 11 (the newest version at that time), and mono and flux libraries. We aimed to migrate applications to a new Java 11 and Spring Boot while preserving the business logic. 

Together we:

  • Performed code refactoring and improved its quality within the newer Java 11 version
  • Helped the client migrate to a future-proofed microservices architecture
  • Upgraded legacy libraries using Spring Boot features
  • Created code coverage reports and performed integration testing
In just 12 months, our team migrated and fully ported 16 legacy services. Our quick and effective modernization of Freenet Group’s systems saved users from downtimes and inconveniences.

Prepare your IT system for market dynamics and growth opportunities!

Industries We Serve

There’s no one-size-fits-all legacy modernization strategy. We treat every project as unique in its challenges and potential, selecting and implementing a modernization plan tailored to both your business needs and industry requirements. 

We understand markets well enough to not just execute a set of instructions but also suggest how to ensure compliance with industry standards, security requirements, and local regulations.

Stages of Our Legacy App Modernization Services

Upon your first contact, our engagement managers will get back to you in no less than 1 day. We will schedule a call to better understand your business needs and technology environment. Then the process will go through the following steps.  

  • 01
    Discovery Phase

    We schedule a series of workshops to audit the state of your current solutions and IT infrastructure. We also identify your project vision, expected modernization results, allocated budget and resources, as well as potential risks and limitations.

  • 02
    Proposal and Project Kick-Off

    We put together a proposal, in which we detail the project scope, modernization strategies, team roles, preferred technologies, anticipated timelines, and recommended cooperation models: staff augmentation, dedicated team, fixed-cost project, or digital transformation. As soon as we agree on the terms, we countersign MSAs and SoWs and begin working on the project.

  • 03
    Implementation

    We now realize the selected legacy modernization strategy: rehost your solution on a virtual/on-prem/cloud environment, migrate to a new runtime platform, restructure the code base, design a new architecture, or rebuild the entire system from scratch. Usually, we follow Scrum methodology with 2-week sprints, where you can continuously review the interim results.

  • 04
    Feedback Collection

    We regularly check if our deliverables satisfy your stakeholders – employees, clients, or users. Upon rollout, we conduct user acceptance testing and incorporate any adjustments or features requested by users.

  • 05
    Maintenance and Support

    We seamlessly transition you to our IT operations services with three levels of technical support, 24/7 system monitoring, and ongoing SRE engineering. We can respond to customer requests as defined by SLAs, troubleshoot complex issues, and develop user-friendly documentation.

How Our Services Stand Out

Extensive Experience
