Double-Take Move 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.
Double-Take Move 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. Double-Take Move 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, Double-Take Move applies the source system state and after a reboot, the source is available and running on what was the target server hardware.
