Windows 11 and
Windows Server 2025.
Windows 11 on the desktop and Windows Server 2025 in the data centre: we supply the licences, plan the migration from Windows 10 and older server versions, set up devices and servers and operate them under a maintenance contract on request. From Berlin and Ahrensfelde, for organisations of every size.
From the licence
to operations.
Licensing advice and supply
Which edition fits (Windows 11 Pro or Enterprise, Windows Server Standard or Datacenter), how many client access licences are needed and where Microsoft 365 already includes rights. You obtain licences through our online shop or with a quote.
Migration to Windows 11
Checking hardware against the Windows 11 requirements, planning the rollout in waves, provisioning via Intune and Windows Autopilot or by image, carrying over applications and data. Windows 10 has not received security updates since October 2025.
Windows Server 2025, new or as an upgrade
Fresh installation or upgrade from Windows Server 2012, 2016, 2019 and 2022 to Windows Server 2025: Active Directory, file and print services, Hyper-V, Remote Desktop and business applications. Server 2016 reaches end of support in January 2027, Server 2019 in January 2029.
Hardening and protection
Secure baseline configuration, encryption, policies, roles and permissions, integration with endpoint protection and backup. A new system is the best opportunity to clean up legacy issues.
Hybrid with Microsoft 365 and Azure
Connect on-premises Active Directory with Entra ID, move server workloads to Azure where it makes sense, and combine workplaces with Microsoft 365.
Operations under a maintenance contract
Updates in planned windows, monitoring, backup checks and helpdesk for users. The scope is in the contract, the costs are transparent in advance.
Planned,
in waves, without downtime.
A typical sequence for workplaces and servers. Operations continue during the changeover.
- Step 1
Inventory
Record devices, servers, applications, licences and dependencies; check what Windows 11 and Windows Server 2025 require.
- Step 2
Target picture and licences
Define editions, client access licences, the order of migration and procurement.
- Step 3
Pilot
One department or one server is migrated first, applications are tested, feedback flows in.
- Step 4
Rollout
Migration in waves, users are informed and trained, legacy systems switched off after a verification phase.
- After that
Operations
Updates, monitoring and support under the maintenance contract, regular reviews.
Frequently asked questions
about Windows 11 and Server 2025.
We still run Windows 10. How urgent is the migration?
Windows 10 has not received regular security updates since October 2025. Devices running it are a risk for the whole network. We check which devices support Windows 11 and plan the replacement of the rest.
Will our business application run on Windows Server 2025?
We clarify that with the application vendor and in a pilot before the migration. Where an application is not yet approved, it temporarily stays on a hardened legacy server or is virtualised.
Can you supply the licences?
Yes. Windows 11, Windows Server and the related client access licences are available through our online shop or with a quote that fits your environment. We check beforehand which rights you already have through Microsoft 365.
Do we still need a server of our own at all?
Not always. Many tasks can be covered with Microsoft 365 and Azure. Where business applications, data storage or latency require a local server, Windows Server 2025 is the current basis. We make a recommendation after the inventory.
What does a migration cost?
That depends on the number of devices and servers, the applications and the existing licences. After the inventory we tell you the effort.
