Data migration is the process of selecting, preparing, extracting, and transforming data and permanently transferring it from one computer storage system to another. . Additionally, the validation of migrated data for completeness and the decommissioning of legacy data storage are considered part of the entire data migrati
The import and export of data is the automated or semi-automated input and output of data sets between different software applications.It involves "translating" from the format used in one application into that used by another, where such translation is accomplished automatically via machine processes, such as transcoding, data transformation, and others.
Data conversion is the conversion of computer data from one format to another. Throughout a computer environment, data is encoded in a variety of ways. For example, computer hardware is built on the basis of certain standards, which requires that data contains, for example, parity bit checks.
The size of the data to be migrated makes the very resource-intensive (Source- Destination- Temporary- storage, network bandwidth, etc.), which means that auditing the migration process could also be complex and require consistency and traceability. Another common issue in content migration is the loss of SEO and page rank in search engines.
Migration (virtualization), the process by which a running virtual machine is moved from one physical host to another; Content migration, the process of moving information to a new system; Data migration, the process of transferring data between storage types, formats, or computer systems
Data discovery is the first step in the data transformation process. Typically the data is profiled using profiling tools or sometimes using manually written profiling scripts to better understand the structure and characteristics of the data and decide how it needs to be transformed.
Migration can be from a mainframe computer which has a closed architecture, to an open system which employ x86 servers. As well, migration can be from an open system to a Cloud Computing platform. The motivation for this can be the cost savings. [1] Migration can be simplified by tools that can automatically convert data from one form to another.
