Database migration to PostgreSQL®
Free yourself from proprietary databases—migrate to PostgreSQL®
Reduce licensing costs permanently and regain 100% control over your database infrastructure. We support your migration from Oracle®, DB2®, Informix® or MS SQL Server®, as well as other databases—securely and in a structured manner. Our migration process is designed for a fast, smooth switchover.
Why keep paying for proprietary databases?
The challenge
Many mid-sized and large enterprises are still locked into expensive, monolithic proprietary database systems. Licensing costs rise year after year—often tied to the number of CPUs, users, or servers. At the same time, pressure is increasing: modern agile software development requires scalable, flexible, and more maintainable platforms. Vendor lock-in limits your strategic options and makes you dependent on individual vendors’ pricing models.
The solution—PostgreSQL®
PostgreSQL® is one of the most advanced and powerful open-source database systems in the world—a fully featured alternative to commercial systems. It is 100% open source and therefore offers 100% cost control: no licensing traps, no surprise price increases, no vendor lock-in. PostgreSQL has been proven in enterprise use for decades, is actively developed by a global community, and meets the highest standards for stability, security, and performance.

Our approach: How your migration works
Replacing a database is not a trivial project—but with the right partner, it is manageable. We divide your migration project into clearly defined phases that ensure transparency and security at every step of the way.
From the initial feasibility analysis to stable operations, you always retain full visibility. We transparently assess business case, risks, and effort—before a single record is moved.
☁️ Cloud or on-premise—your choice
Whether you want to run PostgreSQL® on your own hardware, migrate to a private cloud, or use hyperscalers such as AWS, Microsoft Azure, or Google Cloud—we support you with every approach and work with you to find the optimal architecture for your requirements.
⏱️ Minimal downtime, maximum security
Our migration process is designed for a fast, smooth switchover. With proven tools and an experienced team, we ensure that your production systems are impacted as little as possible during the migration.
🎓 Knowledge transfer for your team
After the migration, we offer tailored training for your developers and database administrators. This ensures your team builds the necessary PostgreSQL® expertise and can operate your new infrastructure independently and competently.
