Cloud migration
Moving systems and data from on-premises infrastructure to cloud services.
Approaches range from lift and shift, which relocates servers as they are, through to re-platforming onto managed services. Lift and shift is fastest and usually the most expensive to run long term.
The costly surprises are rarely the migration itself. They are the application that will not run without a specific old operating system, the bandwidth needed to move the data, and the licensing that changes when the workload leaves your hardware.
Where this comes up
Cloud migration sits inside our microsoft 365 and cloud work. If you are trying to work out what this means for your own environment rather than in the abstract, that is the page worth reading next, and a short call will get you a straight answer faster than either.
