Proven expertise in long-term critical business applications
Code is ageing, skills are becoming harder to find and vulnerabilities are increasing. Moving to the cloud seems necessary, but the application is too important to be stopped. A complete rewrite is expensive and creates concern. You need a partner who understands the business value of the existing application and knows how to modernize it without disruption.
Code consists of many layers added over time, documentation is incomplete and every change takes longer. Business users have to wait, maintenance costs increase and every update creates a risk of regression.
Old framework versions, unsupported libraries and limited security hardening: security debt becomes a risk that neither the IT department nor senior management can leave unresolved in a stricter regulatory environment.
Moving away from on-premise hosting, replacing ageing servers and adapting the application to the cloud: the main challenge is not only technical. It is operational. How can you migrate without stopping the service provided to users and customers?
Strategic vision
An old application is not only a block of outdated code. It also includes business rules, established uses and operational value that is often underestimated. Before we suggest a roadmap, we take the time to understand what needs to stay and what needs to go.
Our Digital Factory works with the main technologies used in the application systems of large organizations: .NET, PHP, Java, Angular, and others. Depending on the situation, we restructure the code, divide the application into modules, or rewrite it in stages using long-term technologies.
Our approach follows one simple principle: modernizing an application must give you more control, not create a new dependency. The source code and project deliverables belong to you. You keep control of business continuity, security and maintainability, and remain free to develop your application with Synidia, your own teams, or another partner.

Controlled modernization
Refactoring, cloud migration and security by design are not three separate projects. Depending on the situation, they can be combined in one modernization roadmap designed to protect the business value of the existing application and prepare for the future.
Key point No. 1
Depending on the situation, we restructure the existing code, divide the application into modules or rewrite it in stages using sustainable technologies. The goal is never to modernize for modernization’s sake. We keep the features that provide business value and replace the elements that slow the application down.
Key point No. 2
Moving local servers, migrating to the cloud and adapting the software: we support you throughout the migration process. The benefit is not the cloud itself. The real benefits are business continuity, security, maintainability and the ability to develop faster in the future.
Key point No. 3
Security is not an afterthought. Our practices follow OWASP standards. We harden applications, reduce the attack surface and include security controls in the development process. For additional support, we work with OPPIDA, our specialist sister company, which carries out penetration tests and security audits.
Synidia has a strong industrial and regulatory background. Our Digital Factory has been active since 2018 and has already worked on strategic Apave Group applications that manage sensitive data at scale. The source code and deliverables remain the property of the customer, providing clear reversibility and long-term freedom to develop the application.

Every modernization project follows a proven structure. The goal is to keep the application operational at every stage and change what must be changed without breaking what already works.
Audit of the code, architecture, dependencies and vulnerabilities. Mapping of business uses and identification of the elements to be protected in the existing application.
Choice between refactoring, replatforming and rehosting. Cloud migration plan when required. Functional stages are prioritized, estimated and planned.
Progressive deliveries, regression testing and user support. The application remains operational at every stage, without any major, high-risk leaps.
Synidia offers Third-Party Application Maintenance contracts for applications developed by us or by another provider. The service is modular and can be adapted to your needs, with a Service Desk based in France and optional bilingual support available 24 hours a day, seven days a week.
Comparison models
Three possible roadmaps, with different balances between risk, cost, time, and expected benefits. The right choice depends on the condition of the code, but also on business needs and your schedule.
| Refactoring | Progressive rewriting | Cloud migration | |
|---|---|---|---|
| When should you consider it? | The code still works but is difficult to maintain | Technical debt is too high and technologies are reaching end of life | Hosting is outdated and more scalability is required |
| Main benefit | Reduce technical debt without breaking everything | Move to sustainable technologies | Improve availability and scalability |
| Operational risk | Low, with delivery in small stages | Controlled when modules are rewritten separately | Must be managed through documented migration windows |
| Typical duration | A few weeks to a few months | Several months, completed in stages | Depends on dependencies and project stages |
| Can it be combined with other approaches? | Yes, often as the first stage | Yes, after the diagnosis | Yes, during or after refactoring |
Frequently asked questions
The main questions asked by CIOs and CTOs before starting a modernization project with Synidia: roadmap choice, risks, cost, security and Third-Party Application Maintenance.
The 7 Rs of application modernization are the main strategies available for developing an existing application. They help CIOs choose the right roadmap according to the condition of the software, its business value, technical constraints, maintenance costs, and its role in the information system.
The seven approaches are generally the following:
It depends on the condition of your application, its business value, your schedule and your target technology. Refactoring reduces technical debt without breaking everything. Rewriting in modules is often the right choice when technologies are reaching the end of their lifecycle. Moving to the cloud is relevant when current hosting limits the application.
In most cases, these approaches can be combined. Our initial diagnosis identifies the right roadmap: first secure the existing application, then reduce technical debt in stages, and finally migrate when required.
This is our guiding principle. All our modernization roadmaps are designed to protect the service provided to business users. We work in functional stages, with systematic regression testing and documented migration windows.
For cloud migrations and other sensitive changes, we document a rollback plan for every step. The application remains operational even if a stage has to be delayed or cancelled.
Our Digital Factory in Skopje covers the main technologies used in the application systems of large organizations: .NET, PHP, Java and Angular. This covers most of the business applications that our customers want to modernize.
If your application uses less common technologies, we assess the situation during the diagnosis. Depending on the context, we can provide additional expertise or recommend rewriting the application with a long-term technology stack.
Security is included from the design stage and is not an afterthought. Our practices follow OWASP standards: application hardening, detailed access rights, strong authentication, reduction of the attack surface, and controls included in the development process.
For the most sensitive applications, we work with OPPIDA, our cybersecurity sister company, for penetration testing and security audits. We have also started an ISO 27001 certification process.
Yes. This is a common situation. We always start with a technical and functional diagnosis to understand the application, its architecture, hidden business rules and actual condition. This stage allows us to suggest a realistic roadmap and provide an estimate for each part of the project.
We can then continue with the modernization project, a Third-Party Application Maintenance contract or both. The goal is for you to have one partner who can reduce technical debt and manage the application over time.
Third-Party Application Maintenance is modular. The standard scope includes corrective maintenance, which covers the resolution of problems, application improvements, and Level 2 and Level 3 technical support.
We can also provide optional hosting and a bilingual French and English Service Desk, available up to 24 hours a day and seven days a week, depending on the selected service level. You remain free to change the scope according to your actual needs.
For modernization projects, we generally work through fixed-price stages or controlled technical support. A fixed price secures the cost and schedule for a clear scope. Controlled technical support is more suitable when the scope changes through short cycles.
For Third-Party Application Maintenance, the commitment is based on documented Service Level Agreements, including response times, resolution times according to priority and availability. You can start with a limited scope and extend it as trust develops.
Synidia is not just any offshore IT services company. We are a software publisher supported by a Digital Factory active since 2018, with a strong industrial and regulatory background from the Apave Group. We understand the industrialization, business continuity and security issues faced by CIOs.
Our mix-shore model combines project management in France with development in North Macedonia, in the same time zone as you. You benefit from the competitive cost of a nearshore factory without losing control of the project. This is especially important in modernization projects where regular communication is essential.
