My name is Tobias Ratschkowski. I am the person behind Unim8trix.

I joined ASWO International Service GmbH in 1992 and spent over 25 years building its IT department from the ground up, later running it as Head of IT. From the first server, through international site networking, to strategic platform choices and people responsibility — that time taught me to see how technology decisions play out years later. For better and for worse.

Platform Migration

Virtualisation and cloud migrations with the least possible operational disruption. From inventory audit through target architecture to cutover and support through to handover.

When this fits: When an existing platform is hitting its limits — licensing costs, scalability, vendor lock-in, consolidation pressure. Or when a cloud exit is on the horizon. Or when historically grown structures need to become a hyperconverged platform.

What you get: A robust migration strategy that names risks instead of hiding them. A target architecture that works in practice, not only on paper. Hands-on support during the hot phase, when real data is flowing.
