Storage Mirroring Data Migration
overview
Storage Mirroring Data Migration is a comprehensive workload migration solution. It
allows you to move an entire server, known as a source, by mirroring an image of that
source to another server, known as the target. The source and target servers can be
physical or virtual. The image of the source contains the server's system state (operating
system, server configuration, and installation applications) and all of the source server’s
data. You can also migrate just a source's data, in which case the target's system state
(operating system, server configuration, and installed applications) will be used with the
source's data.
Storage Mirroring Data Migration uses patented data replication technology that allows
users to continue accessing and changing data during the migration. As changes are
made on the source, replication keeps the image of the source stored on the target up-to-
date. Storage Mirroring Data Migration replicates, in real-time, only the file changes, not
the entire file, allowing you to more efficiently use resources. When you are ready to
cutover to the new server, Storage Mirroring Data Migration applies the source system
state and after a reboot, the source is available and running on what was the target
server hardware.
