Cloud migration services for systems that cannot afford a bad weekend.
We move workloads in an order that keeps the business running, and we say which ones should not move at all.

Rollback rehearsed before the cutover that matters
Migrations rarely fail technically. They fail in the order things moved.
Cloud migration is not always the right project. A system that is slow because of how it is built will be slow in a new environment too.
The dependency nobody mapped
One system moves, and three others that quietly depended on it start failing in ways that take days to trace.
Lift and shift, then a bigger bill
Everything moves as it was. Nothing is sized for the new environment, and the saving turns into an increase.
A cutover with no way back
The rollback was a plan rather than something tested, so the decision to continue gets made under pressure.
What we take on.
The six pieces of a migration we own, from the first dependency map to the day your own engineers operate it.
Dependency and readiness mapping
What talks to what, what holds state, and what breaks if a system is unavailable for an hour.
Migration sequencing
The order of moves, chosen so each one can be verified before the next begins.
Application migration
Services moved and re-sized for the target environment rather than copied at their current shape.
Data migration and cutover
Movement, verification and a rehearsed cutover, including the path back.
Post-move optimisation
Right-sizing after real traffic, which is the point at which most of the cost story is decided.
Handover to your team
Environments described in code and operable by your engineers, not by us.
Where this page stops: pipeline and release work is DevOps consulting, and re-architecting the application is modernisation. This page owns moving what exists, safely.
See system modernisationFive options per system, not one decision for the estate.
Treating a migration as a single choice is what produces both the surprise bill and the outage. Each system gets its own answer, and some of the answers are cheaper than moving.
Move as-is
Relative effortWhen it fitsStable system, near end of life, low change rate.
What it costs you laterRuns unchanged, so none of the environment's advantages apply.
Move and re-size
Relative effortWhen it fitsWorks well, sized for hardware you no longer have.
What it costs you laterModest rework now, most of the cost benefit realised.
Re-architect
Relative effortWhen it fitsChanges often, and the current shape is the constraint.
What it costs you laterLargest effort. Only justified where change is frequent.
Replace with a product
Relative effortWhen it fitsThe system does something standard, badly.
What it costs you laterMigration of data and process, not of software.
Leave it
Relative effortWhen it fitsStable, isolated, and moving it buys nothing.
What it costs you laterNothing. This is a legitimate answer and it is often the right one.
We produce this table for your estate before any system moves. The systems in the last row are usually the ones that make a plan credible.
How a migration runs.
A disciplined order. Each move is verified before the next begins, and the path back is rehearsed before the cutover that matters.
Inventory and dependency map
What exists, what depends on it, and what the business cannot be without. Built from the running systems, not from a diagram someone drew once.
Decide per system
The five options above applied to each workload, with the reason recorded so it can be challenged.
Move the least critical thing first
Not the easiest and not the most valuable. The one that teaches you most about the target environment at the lowest cost of being wrong.
Rehearse the cutover that matters
Including the path back. A rollback that has never been executed is an assumption.
Move, verify, then re-size
Verification against agreed checks before the next move. Sizing decided on real traffic, not projected traffic.
Hand over what you now operate
Environments in code, runbooks written with your engineers rather than for them.
Where this stops. Rewriting or re-architecting the application belongs to legacy system modernisation. This page owns moving what exists, safely.
See system modernisationWhat we can show, and what we cannot.
We have no published cloud migration case study with a measured outcome. Rather than attach a number from unrelated work, here is the record that is relevant to running systems long-term.

A nine-year integration is an operations record rather than a launch record, which is the relevant kind of evidence for work that has to keep running after the migration.
See all case studiesWhere migrations usually start.
Framed as situations rather than industries. We hold no sector-specific migration evidence and will not imply otherwise.
A datacentre contract ending
Where the deadline is external and the sequencing decision is the whole project.
A bill that grew without a decision
Where systems were moved as-is and nothing was re-sized afterwards.
A system nobody will touch
Where the risk of moving it is the reason it has not moved, which is also the reason it must.
An acquisition to absorb
Where two estates now have to run as one and the overlap has not been mapped.
The cost conversation, before the move rather than after it.
We do not publish cost figures because they depend entirely on your estate. We do commit to naming which systems are likely to cost more before anything moves.
- After the move
Sizing is decided after real traffic
Pre-move estimates are guesses. The first weeks of actual load are what the sizing decision should be based on.
- One-off
Data movement is a one-off cost with a shape
Volume, frequency and direction all matter. Worth knowing before, not on the first invoice.
- Ongoing
Some systems get more expensive
Steady predictable load can cost more in a metered environment. We name which of your systems those are.
- Only if rushed
Two things change at once, and only one is measured
Migrating and re-architecting together makes it impossible to attribute either the saving or the regression.
What you have when the migration ends.
We close with a record, not an assurance. This is what is left behind.
The per-system decision record
Every workload, its chosen option and the reason, so the next person inherits the thinking.
Environments described in code
The target estate defined and reproducible rather than hand-built.
A rehearsed rollback, documented
Including the one you did not need to use.
Reconciliation evidence
Proof that data matched after the move, not an assurance that it should have.
A decommissioning list with owners
What is switched off, what is retained, and who confirmed it.
Who we need from your side.
If those four people are not available, that is worth knowing before a plan is written rather than during it.
Undocumented behaviour lives with the people who run it today.
Someone who can decide
Migration plans stall on sequencing decisions. One person needs to be able to settle them.
Whoever runs it today
Undocumented behaviour lives with them, and mapping without them is guesswork.
A security or compliance reviewer
Involved early, because residency questions raised late change the plan rather than approve it.
Whoever owns the budget
Because per-system decisions have cost consequences that should be visible as they are made.
What teams ask before they start.
Pick a topic, or ask us directly. We answer every inbound within one business day.
Still have questions?
Talk to a senior engineer, not a bot.
Start with the system you are most afraid to move.
Tell us which workload keeps the migration plan stuck. We will say which of the five options fits, and tell you plainly if the answer is to leave it where it is.
