Migration planning
An inventory of every system, its dependencies and the right route for each.
Cloud migration · Performance
Cloud migration services
Move legacy systems to the cloud without the weekend outage or the surprise bill. We plan each system’s move, do the work and tune it once it’s running.
Not every system should move the same way
Some applications can be lifted to the cloud almost as they are. Some need a new database or a container first. A few are worth rebuilding. Treating them all the same is how migrations run over time, over budget, or both.
We look at each system and pick the route: rehost, replatform or refactor. Then we move them in a sensible order, test each one under real load and keep a way back until it’s proven. After the move we tune performance and cost, because the first cloud bill is rarely the right one.

What we do
Migration and cutover
Moves done in stages, with rehearsals and a rollback plan for each one.
Multi-cloud and hybrid
Architectures that span AWS, Azure and your own servers where needed.
Cost optimisation
Right-sized resources, reserved capacity and clean-up of what nobody uses.
Cloud-native rebuilds
Containers and Kubernetes for the systems worth modernising.
Security and disaster recovery
Access control, encryption, backups and a recovery plan that has been tested.

How we work
- 1
Assess
Inventory of systems, data, dependencies and current costs.
- 2
Plan the routes
Rehost, replatform or refactor for each system, in a safe order, with a budget.
- 3
Migrate in waves
Each wave tested under load, cut over in a quiet window, with a way back.
- 4
Optimise
Performance and cost tuning once real traffic is running.
Questions we often get
What’s the difference between rehost, replatform and refactor?
Rehost moves an application as it is ("lift and shift"). Replatform makes small changes, such as switching to a managed database. Refactor rebuilds parts of the application to use cloud-native services. Most migrations use all three for different systems.
Will we have downtime?
We plan each cutover to keep downtime to a short, scheduled window, and for many systems we can switch with none at all.
Will the cloud be cheaper?
It can be, but not automatically. We size resources from real usage, remove waste and set up cost alerts, so the bill is known and justified.
AWS or Azure?
Both work well. The best choice usually depends on your existing licences, skills and tools. We’re happy on either, or both.
What does a migration cost?
It depends on how many systems there are and how much change each one needs. After a free 30-minute call we send a plan and estimate, usually within a week.
