Moving
data from one system, or
domain, to another without compromising security or losing any of the data. Domain migration happens when
servers are upgraded and the data (including any
authentication and
authorization information) must be moved to a new system, when an administrator changes from one
ISP to another or when an Web site’s administrator moves the data that creates a Web page (any mark-up language coding and images) from one system, or domain, to another.
