Your infrastructure project, without the drama.

Replacing servers, refreshing a network, or moving to the cloud sounds disruptive. Done properly, it is not: almost all of the work happens alongside your live systems, and the actual switch is a planned window you approve, with a rollback plan sitting ready. This page shows you the whole journey, phase by phase.

The journey

Six phases, two decisions.

The map

Whether it is one server or a whole environment, the shape is the same. You make two decisions: which direction to take, and when to cut over. Everything else, including the risk, is ours to manage.

1

The conversation

30 to 45 minutesNo charge

What is driving the change: hardware reaching end of life, an office move, growth, a lease ending, or simply costs that no longer make sense. We listen first, because the driver shapes the answer. Cloud is not always it, and we will say so when it is not.

What we need from you
  • What is prompting the change, and any hard dates attached to it
  • What must not break: the two or three systems your business stops without
You leave withA clear next step, and an early read on the realistic options.
2

Assessment

Typically 1 to 2 weeks elapsed

We map what you actually have: every server, application, data store and connection, who uses what, and what depends on what. Migrations go wrong when a forgotten dependency surfaces mid-cutover, so this phase exists to make sure nothing is forgotten.

What we map
  • Servers, storage, applications and how they depend on each other
  • Data volumes, and how fast they can realistically move
  • Connectivity: whether your internet and network can carry the result
  • Backup state, so there is a safety net before anything moves
What we need from you
  • Access to the environment (read-only)
  • The person who knows each key application

You leave withA written picture of your environment and the options on the table: cloud, hybrid, or an on-site refresh, each with its trade-offs.

Design & scoping: the plan and the price

Price is fixed here

You choose the direction; we design the destination in detail and put a fixed price on getting there. The scope also states the new monthly running costs, so you are comparing whole pictures, not just project prices. Old monthly spend versus new monthly spend, side by side.

The scope names
  • The target design, and each phase with its hours
  • What moves, in what order, and what is retired
  • Cutover windows, and the rollback plan for each
  • New monthly running costs next to your current ones
  • The payment schedule
What we need from you
  • The direction call: cloud, hybrid or refresh
  • Blackout dates: payroll runs, end of month, your busy season
You leave withA fixed-price proposal with the running costs itemised. It does not move unless you change the scope, in writing.
Decision point · yours
Approve the plan, the price and the dates.

Nothing is ordered and nothing moves until you approve the scope. If the numbers say the old servers should run another year, that is a fine outcome, and you keep the assessment either way.

Build & stage

Zero disruption

The new environment is built next to the old one, not on top of it. Cloud tenancy or new hardware is stood up, security is configured, and your data starts syncing across in the background while everyone keeps working on the current systems. We test migrations on copies before any real cutover.

What happens
  • New environment built and secured in parallel
  • Data seeded and kept in sync in the background
  • Test migrations run on copies, timed and verified
  • Key applications proven in the new home before anyone relies on them
What we need from you
  • A couple of testers to try their day-to-day work in the new environment
  • Sign-off that the test results look right
Share of total effort~40 to 50%
You leave withA proven, tested destination, and a cutover plan rehearsed rather than hoped for.

Cutover

You approve the windowUsually out of hours

The switch itself. It happens in a window you approve, usually an evening or weekend, with your team told exactly what to expect and for how long. A final data sync runs, systems are pointed at the new environment, and everything is tested before Monday morning. If anything material fails the checks, we roll back to the old environment and your team starts the week as if nothing happened.

In the window
  • Final sync, switch, then a full test checklist
  • The old environment held intact as the rollback
  • You are told when it is done, not left wondering
What we need from you
  • The go decision for the agreed window
  • A contact we can reach during the window
Share of total effort~15 to 20%

Hypercare & handover

First weeks, intensive

The first days after a cutover get extra attention: we watch closely, fix the small things fast, and check in with your team rather than waiting for tickets. The old environment is only decommissioned after you have signed off that everything works, and the documentation of your new environment is written into your runbook, not left in someone's head.

What ongoing looks like
  • Priority response in the first weeks after cutover
  • Old systems retired only after your sign-off, then securely wiped
  • Documentation updated, monitoring and backup proven on the new environment

Paying for it

Payment, and what changes monthly.

Agreed at scoping
01 / Project
Staged against milestones.
Project payments follow the phases: a portion to begin, then payments tied to milestones you can see, with hardware invoiced as it is ordered.
02 / Spread monthly
Finance the refresh.
Through IT asset finance, hardware, licensing and the project itself can become one predictable monthly cost.
03 / Running costs
Old monthly vs new monthly.
Cloud is a consumption bill; on-site is power, warranty and eventual replacement. Your scope puts current and future monthly costs side by side before you decide.
Cost
What it is
Decided
Cloud consumption
The monthly bill for what you actually use in Microsoft 365 or Azure. Sized in the scope from your real data and workloads, then reviewed after go-live so you are not paying for headroom you do not need.
At scoping, phase 3
Licensing changes
Moving platform often changes licence shape: server licences retire, per-user subscriptions arrive. Named in the scope, both directions.
At scoping, phase 3
Connectivity
Cloud shifts the load onto your internet connection. If yours needs an upgrade to carry it well, that is stated up front, with its monthly cost.
At scoping, phase 3
Decommissioning
Retiring old kit properly: secure data destruction, licence tidy-up, recycling. Included as a line in the plan, not an afterthought.
In the project price
Two worked examples

A single server, and a whole environment.

Sample plans
Sample plan A · smaller engagement
One server to the cloud.
An ageing file or application server moved into Microsoft 365 or Azure. The most common first migration, and usually the end of the server room heater.

These are illustrations, not quotes. Every environment is different, and your project is scoped individually with a fixed price and agreed cutover windows before anything moves.
The deal

What you can hold us to.

Both ways
What you can expect from us
  • A fixed price and named cutover windows before anything moves
  • The new environment proven with test migrations before the real one
  • A rollback plan at every cutover, and the old system kept until you sign off
  • New monthly running costs shown next to your current ones, up front
  • Your team told what to expect, in plain language, before every window
What we ask of you
  • Access, and the person who knows each key application
  • Blackout dates and the busy periods we must work around
  • A couple of testers before cutover, and a contact during it
  • Sign-off at the decision points, so the project keeps moving

Start with the
assessment.

A conversation costs nothing, and the assessment gives you a clear picture of your options whether or not you go ahead. No pressure either way.

And relax

Getting started is the easy part.

Onboarding without drama

We do the switch: your current provider, the migration, the handover, all of it. Most teams barely notice the cutover happened.

Everything looked after

On the right plan, compliance, reporting and budgets are handled inside the partnership. You run the business; we run the IT underneath it.

Your QBR writes itself

Quarterly business reviews are generated automatically from your live environment: spend, posture, recommendations and roadmap, ready for the board, reviewed with your account manager.

The honest bit: the full looked-after experience comes with the right plan. We charge fairly for what we take on, and when costs step up it's because you are taking on more, always moving in the right direction.
