Data migration is the process of moving data from one location to another, one format to another, or one application to another.
Data migration is important because it is a necessary component to upgrading or consolidating server and storage hardware, or adding data-intensive applications like databases, data warehouses, and data lakes, and large-scale virtualization projects. Data migration may also occur within systems built on HDD or SDD, or between in-house systems and cloud storage.
These days, data migrations are often started as firms move from on-premises infrastructure and applications to cloud-based storage and applications to optimize or transform their company.
Types of Data Migrations
There are numerous business advantages to upgrading systems or extending a data center into the cloud. For many firms, this is a very natural evolution. Companies using cloud are hoping that they can focus their staff on business priorities, fuel top-line growth, increase agility, reduce capital expenses, and pay for only what they need on demand.
Storage Migration is a function that migrates the volume data from an old storage system to volumes in a new storage system without using a host in cases such as when replacing a storage system.
Storage Migration provides two data migration methods: online & offline. With offline, operations must be stopped in the storage systems during a data migration and with online, the data can be migrated while performing operations.
Cloud migration is the process of moving data, applications or other business elements to a cloud computing environment. There are various types of cloud migrations an enterprise can perform.
The process of moving data, application, or other business elements from either an on-premises data center to a cloud or from one cloud to another. In many cases, it also entails a storage migration.
Application migration is the process of moving an application program from one environment to another. May include moving the entire application from an on-premises IT center to a cloud, moving between clouds, or simply moving the application's underlying data to a new form of the application hosted by a software provider.
