The process of moving data from one location to another is known as data migration. This could involve moving data across applications, databases, storage systems, or a variety of other formats and platforms. Data preparation, extraction, and transformation are frequently included in the data migration process to make data transfer-ready.
The main objectives of data migration are to guarantee correct and comprehensive data movement, reduce data downtime, and cut migration expenses. Website consolidation, legacy system upgrades or replacements, the adoption of a cloud-based system, infrastructure maintenance, or the consolidation of information systems are examples of common data migration situations.
Data Migration Types by System Format
It's important to understand that depending on the type of data moving as well as the source and target systems involved, some steps will need to be added or reworked. This is true even though many data migration best practices and strategies will remain the same regardless of the data format or system type they're working with.
Database or Schema Migration
A database or schema migration takes place when a database schema is modified to work with an older or more recent version of the database. Data transformation methods are frequently a crucial component of this kind of transfer because many businesses still employ outdated file and database formats.
Storage Migration
Datasets are transferred from one storage system or format to another as part of this kind of project. These days, this frequently entails transferring data from a standard hard drive or tape to a higher-capacity drive or the cloud.
Data Center Migration
An entire data centre is relocated during a data centre migration, either to a new physical site or to a new non-physical system, such as the cloud. Due to the size of the project, thorough data mapping and preparation are required for a successful migration.
Cloud Migration
Organisations may migrate to the cloud from on-premises legacy systems or may switch from one cloud provider to another. In this form of migration, applications, databases, and several other corporate assets will all need to be migrated.
Application Migration
Applications may need to be moved from one environment to another during this type of migration, but datasets may also need to be moved from one application to another. This kind of migration frequently happens concurrently with cloud or data centre migrations, but it can also happen, for instance, when they transfer vendors for a project management tool.
Business Process Migration
Business process migration is employed, particularly during mergers and acquisitions as well as other significant business changes, to ensure that all information is shared with the target system and acquiring organisation. Depending on the sector and location, this kind of migration may place a special emphasis on data governance and security measures.
