Enterprise cloud migration

Changing foundations without stopping the machine.

A failed migration shows immediately: outages, runaway bills, exhausted teams. We run migrations in waves, with a tested rollback plan at every step. Your users should notice nothing, and that is the only success metric that truly counts.

01

Zero planned downtime

Progressive cutovers, temporary dual-running, controlled DNS switching. Your customers keep buying while we move house.

02

Guaranteed reversibility

Every wave has a tested rollback plan. If a step goes wrong, we revert in under an hour.

03

Predicted, not endured, billing

Target cost modelling before migration, then weekly tracking. No nasty surprise on the first invoice.

04

Your teams level up

Your engineers take part in each wave. By the end, they run the platform without us.

Our method

01

Inventory and mapping

We catalogue applications, dependencies, flows and data. What nobody has documented for five years finally becomes visible.

02

Per-application strategy

Rehost, replatform, refactor or retire: each application gets the strategy that minimises risk and total cost.

03

Waves and stabilisation

Migration in batches of increasing complexity, with an observation period between each wave.

Frequently asked questions

For an SME information system, expect three to six months. For a more complex estate, migration spreads over twelve to eighteen months in successive waves.
