Legacy Modernisation & OS Migration
From Windows 10, Windows 7 and end-of-life servers to Windows 11 and the latest Windows Server, even when the install media is long gone.
Bring legacy systems safely up to date
The real blocker to leaving an unsupported operating system behind usually isn't the OS. It's the one legacy application nobody's touched in years that only runs on it, and that nobody has the install media for any more.
Unsupported servers and applications don't fail gracefully, they fail during an audit, a compliance review, a cyber-insurance renewal, or a hardware death with no vendor left to call. Every month on an unsupported OS is unpatched risk, rising cost and, increasingly, an avoidable carbon footprint on ageing kit.
Unsupported operating systems are a serious security and compliance risk, but migrating away from them is rarely straightforward. We move you off Windows 7, Windows 10 and end-of-life Windows Server (2008, 2012, 2016) onto modern, supported platforms.
We handle the whole journey, from Windows 11 rollouts to upgrading old servers to Windows Server 2022 or Azure, resolving legacy application compatibility along the way. Where the install media is gone, we capture the application from its running state with EtherApps Forge and repackage it for a modern OS, so nothing gets left behind.
Legacy application capture and repackaging is delivered with EtherApps Forge from our partner EfficientEther.
Everything you need, managed for you
Questions we hear a lot
Can you migrate a legacy app if we've lost the install media?
Yes. Using EtherApps Forge, we capture the application directly from its current, working installation, packaging its actual installed state rather than needing the original setup media or source code. That capture is then deployed and tested on a modern, supported operating system.
Should we migrate a legacy application or rewrite it?
It depends on runway. A full rewrite is often a twelve-to-eighteen-month project, and an app on an already-unsupported OS rarely has that time. Capture-based migration gets it onto a modern platform in weeks, which can be the destination or a safe bridge while a rewrite happens on its own timeline.
What are the risks of staying on an unsupported operating system?
Unpatched security vulnerabilities, failed compliance and cyber-insurance requirements, no vendor support when hardware fails, and a growing energy and carbon cost from keeping ageing kit running. The risk compounds every month, usually surfacing at the worst possible time.
