What is the definition of database migration?

Database migration refers to the process of transferring data between storage types, formats, or systems. This can involve moving data from one database management system to another, changing the format in which the data is stored, or transitioning to a different storage environment altogether.

Migration is often necessary when an organization upgrades its database systems, consolidates databases, or needs to integrate new data sources. The process ensures that the data remains accurate and accessible in its new location, which can involve complex tasks such as data transformation, validation, and testing.

The focus on transferring data is critical because successful migration requires not only moving data but also ensuring that it continues to function properly in its new environment. This definition encompasses a broad scope, allowing for various strategies and methodologies tailored to the needs of the organization.
