Domain Migration

Definition - What does Domain Migration mean?

Domain migration is the shifting or migration of data between domains without data security loss or impairment. Data may be migrated in multiple formats, such as text, Internet and authorization/authentication files.

After migration, preserving data in a usable format requires special attention. Files must be transferred in the correct format with appropriate file extensions. Administrators also should take steps required to preserve correct data ownership and assigned file permissions.

Many ISPs and Web hosting services offer domain migration management services.

Techopedia explains Domain Migration

Domain migration is required under the following conditions:

  • During server upgrades, when server data must be transferred to a new system for preservation
  • When an administrator switches to a new Internet service provider (ISP)
  • When a website administrator migrates data Web page data from one domain to another

The domain migration process varies by server type during a server upgrade. For example, Unix and Windows servers may undergo different domain migration processes. The same rule applies to ISPs and Web hosts.

File Transfer Protocol (FTP), a typical domain migration method, allows users to download local system files and upload files to a new server. However, FTP has a number of deficiencies that make it less than ideal, as follows:

  • During data transfer, FTP does not provide adequate preservation tools.
  • File formats with unknown file extensions may be altered during FTP transfers.
  • FTP only facilitates data transfer in uncompressed formats, which leads to system resource waste.
