Common questions

Will my server stop working on the deadline?

No. It keeps running, but it stops receiving security fixes, so the risk grows the longer it stays in use, especially if it's reachable from the internet.

Can't I just pay for more updates?

For 2012 / 2012 R2, the paid Extended Security Updates end on 13 October 2026 and there's no further option. For 2016, check Microsoft's current offer, but it's usually a costly stop-gap rather than a plan.

How long does a move take?

For a typical office of 5–25 people, 4–8 weeks from the assessment to switching the old server off, with a pilot group first and the switch done out of hours.

What if our software has to run on a server?

We'll check with your software supplier. Many now accept a cloud server (Azure, UK data centres) or have a cloud version. Where it really must stay in the office, we'll make sure it's on a supported, backed-up server.
