What Is Cloud Migration?
Cloud migration is the process of moving digital assets — such as data, applications, and IT processes — from on-premises infrastructure to a cloud environment (public, private, or hybrid). It can also involve moving from one cloud provider to another (cloud-to-cloud migration).
