Windows Server migration to Azure
Windows Server migration to Azure moves your 2012, 2016 and 2019 servers onto Azure virtual machines in UK South or UK West, and onto a supported version. Windows Server 2016 support ends on 12 January 2027. We start with a free assessment, then plan a route for every server.

Email the teamDo we have to upgrade Windows Server when we move to Azure?
Not on the day, but it's the lasting fix. Azure Migrate can upgrade 2016 to 2019 or 2022 as it moves, and an Azure VM can later go to 2025 in place. Left on 2016, a server needs paid Extended Security Updates from 12 January 2027.
Can we reuse our Windows Server licences in Azure?
Often. Azure Hybrid Benefit covers Windows Server licences with Software Assurance or a qualifying subscription, with at least 8 core licences per VM.
Will there be downtime?
A short planned outage per server. Azure Migrate copies each server while it runs, then shuts it down for a final sync at cut-over, in a window you agree.
What if our application vendor doesn't support Azure?
We check vendor requirements in the assessment and, if needed, test the application in Azure before you commit.
