Frequently Asked Questions
FAQ about Legacy Modernization
Basics & Assessment
How do I know if my software needs modernization?
Typical signs: Increasing maintenance costs, performance problems, lack of interfaces, security concerns, or the technology is no longer supported. We offer a free initial assessment.
Can you also modernize software without documentation?
Yes, we regularly take over systems where only the code exists. Through reverse engineering and structured analysis, we understand the logic and document it for the future.
Strategy & Approach
Rewrite or refactor – what do you recommend?
Depends on the situation. Often a gradual migration makes sense: new functionality on new technology, old system runs in parallel until it's replaced. We analyze costs and risks with you.
Can existing data and processes be preserved?
Yes, that's usually the goal. We plan data migration carefully, validate quality, and ensure no business-critical information is lost.
Plan modernization? We analyze your system and develop a pragmatic migration strategy.
Schedule ConsultationCosts & Timeline
What does a modernization project cost?
Highly dependent on scope and complexity. A small application from 15,000 €, larger enterprise systems correspondingly more. We start with an assessment to get a realistic estimate.
How long does modernization take?
Small systems: 2-4 months. Complex migrations: 6-18 months. We work in sprints and deliver usable results early, so you can see progress and give feedback.
Risk & Security
How do you minimize the risk of failure?
Through gradual migration, parallel operation of old and new systems, comprehensive testing, and rollback strategies. We never switch everything at once.
What happens if the original developers no longer exist?
Not uncommon with legacy systems. We work ourselves into the code, analyze structure and logic, and build a new knowledge base. This takes time but is feasible.
Questions about modernization? We advise honestly about possibilities, costs, and risks – from experience with many legacy projects.
