Definition
Migrations refer to the process of moving data, applications, or entire IT systems from one environment to another. This can involve shifting from on-premises infrastructure to cloud services, upgrading hardware, or consolidating data centers. Understanding migrations is crucial for IT professionals as it directly impacts system availability, data integrity, and operational efficiency. For instance, a company might migrate its customer relationship management (CRM) system from an outdated on-premises server to a modern cloud-based SaaS solution. This differs from simple data backups, which are for recovery, whereas migrations are about active system relocation. Concepts related to migrations appear in domains like IT infrastructure and cloud computing on various certifications.
