One typical paradigm for cloud migration involves moving data and applications from an on-premises data center to the cloud, but it is also possible to move data and applications across different cloud platforms or providers. Cloud-to-cloud migration is the term for this second situation.

Cloud Migration for Businesses
Data, programs, and other business components are moved into a cloud computing environment through a process known as cloud migration.
If you're anything like the majority of businesses, at least one workload exists on the cloud for you already. But as you'll see, not every case calls for the significant change that a cloud migration brings. Although there should be more factors influencing your choice than only scalability, dependability, and ease of use, cloud environments are typically these qualities.
