Medical practice IT: email, practice software and network changed over

Since February 2026 I have been supporting a specialist medical practice in Hamburg with ten workstations at two sites. Domains, mailboxes and distribution lists had built up over the years at a web host, the practice software was due for a system change, and the network kept dropping out. Every change had to happen while the practice kept running, and patient data sets the boundaries.

I first recorded every domain, mailbox and distribution list so no address would go missing in the move. Then the seven mailboxes from two domains moved to a platform with built-in protection against phishing and malware, coordinated with support on both sides. Beforehand I archived every mailbox, current and old, in a local archiving solution, so the contract with the previous web host could be cancelled without losing old emails. I planned and accompanied the migration of the practice software to Tomedo together with the vendor. The network got a firewall with separate zones and, after a fault analysis with vendor support, a cleaned-up, documented configuration.

Email runs on the new platform with its protection features, and old mailboxes are archived. The practice software runs on the new system, and the network is reconfigured and documented. For email, the network and coordination with the providers, the practice has one point of contact. Since the changeover I have looked after the practice on an ongoing basis. Some recommended measures have not yet been implemented, at the practice’s request.
