Cloud migration has a reputation problem. The case studies you hear about tend to fall into two categories: the ones that went brilliantly and the ones that went catastrophically. The difference between them, in our experience, is almost never the cloud platform — it is the quality of the planning and the rigour of the execution.

The Three Migration Strategies

Most migrations involve some combination of three approaches. Lift-and-shift moves your existing system to the cloud with minimal changes — fast and low risk, but you do not get the full benefit of cloud-native architectures. Re-platforming makes targeted optimisations during the move. Re-architecting rebuilds the application to be cloud-native — the highest effort but the greatest long-term benefit.

The Discovery Phase Is Not Optional

Every migration horror story we have encountered had the same root cause: the team underestimated what they were actually migrating. A thorough discovery phase — mapping every component, its dependencies, data volumes, and availability requirements — is not overhead. It is risk management.

Migrate in Phases, Not in One Big Bang

A phased approach, migrating one service or subsystem at a time, dramatically reduces risk. Each phase can be tested and validated before the next begins, and rollback is always an option if something does not behave as expected.

The People Side

The technical work of a cloud migration is only half the story. Your operations and support teams need to be upskilled, runbooks need updating, and monitoring needs reconfiguring.
