Use Case

Migrate from Microsoft 365

Digital sovereignty starts with a decision.

Microsoft 365 is convenient – but also expensive, creates dependency, and is problematic for data protection. Schleswig-Holstein shows: there's another way. The state saves €15 million in license costs per year with open source.

Why Migrate?

Costs

Microsoft regularly increases prices. Cloud mandates make it even more expensive. With 50 users, easily 5 figures per year.

Dependency

Once in, hard to get out. More lock-in every year through new features that only work in the Microsoft ecosystem.

Privacy

Data sits in US clouds. Legally questionable after Schrems II. A real problem for government and sensitive industries.

Control

You don't know what happens with your data. No insight into the code. No ability to customize.

The Alternative
