Software Modern­iza­tion: Bringing Legacy Systems Safely into the Future

The cost depends mainly on the condition and scope of the legacy system. We usually implement modernizations of individual applications or modules in the Professional package from €8,000, and we quote extensive legacy migrations individually in the Enterprise package. You receive a reliable quote after the free initial consultation and the assessment.

The duration depends on how many modules, data sets and interfaces are being moved. Because we work in stages, you often benefit after the first migrated module, while the rest follows on a predictable schedule. We prepare a timeline after the assessment.

If the business logic is right and the code is fundamentally well structured, modernization is usually more cost-effective. If the architecture is no longer viable, a rebuild can be cheaper – and even then we carry over the existing rules and data. After the analysis, we tell you openly which route is worthwhile.

Yes. We take over bug fixes, security updates, backups and monitoring for existing applications – even if another provider developed them. That keeps your operations stable until the modernization is complete.

Our goal is a complete transfer. We back up the legacy system beforehand, transfer the data in test runs first and compare samples with the original. The switchover happens only after you have reviewed the results.

Missing documentation is more the rule than the exception with legacy systems. We reconstruct the structure and workflows from the code, the database and conversations with your users. If even the source code is missing, we assess together which options are technically possible – please clarify questions about rights to the code separately. This does not replace legal advice.
