When the original Primary fails or is destroyed because of a disaster, the takeover procedure enables you to convert a consistent Secondary to a Primary.
To determine whether the takeover of the Primary by a Secondary is successful, you must first consider whether the data is consistent and how up-to-date it is.
Volume Replicator provides the takeover operation to transfer the Primary role both from the graphical user interface as well as the command line. Upon successful completion of the takeover, the Secondary becomes the Primary.
