Infrastructure Modernization

Moving servers, hypervisors and operating systems off versions that no longer receive security updates.

Most infrastructure work starts with a date somebody else chose: a support cut-off, a renewal, an audit finding. The technical problem is rarely the hard part. The hard part is knowing what you have, what depends on it, and which order things can safely move in.

Who it is for

Companies running their own servers, on-premise or in a colocation rack.
IT managers who have been given a date when a platform stops being supported.
Finance leads looking at a renewal quote that is larger than last year's.
Teams with no dedicated infrastructure engineer on staff.

Typical situations

The renewal quote arrived and the number changed

A virtualisation or database renewal comes in well above the previous term. The platform still works, so there is no technical reason to move — only a commercial one, and a deadline set by somebody else.

A version reaches end of support on a known date

Security patches stop on a published date. The system usually keeps running perfectly well after it, which is what makes this easy to defer until an auditor, an insurer or a customer questionnaire forces the issue.

Nobody is certain what is actually running

The inventory is a spreadsheet somebody maintained until they left. Before anything can move, the first job is establishing what exists and what depends on it.

There is one machine nobody wants to restart

An old server runs something the business depends on, and the people who built it have gone. Planning around that machine usually matters more than planning the rest of the estate.

What we deliver

A written inventory of hosts, guests, operating system versions and support status.
A dependency map showing which systems talk to which, and what stops if one does.
A migration sequence, with the risky items named as risky and scheduled separately.
A rollback plan for each step, tested before that step runs.
The migration itself, carried out in agreed windows.
Handover documentation written for your team to use without us.

Typical timeline

A fixed-price assessment usually takes one to two weeks once read-only access is granted. Implementation duration is set out in the assessment report and depends on scope and change windows.

Starts with a fixed-price assessment

Read-only access first, so nothing changes while we look. You get a written finding, a recommendation and a price before any work is agreed. If the finding is that you should do nothing yet, that is what it will say.

Common questions

Do we have to replace everything at once?

No. This work is done in stages, and the sequence matters more than the speed. The usual approach is to move the low-risk systems first, confirm the process works, then handle the awkward ones with more time.

What happens to the system nobody wants to touch?

It gets planned around rather than ignored. Sometimes the right answer is to isolate it and reduce what it is exposed to, instead of migrating it. That is a legitimate outcome, as long as it is a decision rather than an accident.

Will there be downtime?

Usually some, and it is agreed in advance rather than discovered. Part of the assessment is working out which systems can move without an outage and which cannot, so the windows are known before any work starts.

Can you work alongside our existing IT provider?

Yes. Where there is an incumbent provider or an internal team, the work is scoped around them, and the handover documentation is written so they can operate what has been built.

What if the assessment concludes we should do nothing yet?

Then that is the finding, and you have it in writing. Deferring is sometimes the correct call, and knowing the real deadline is worth more than starting work early.
