MIGRATING DATA BETWEEN HETEROGENEOUS CLOUD BLOCK DEVICES

Abstract: a migration management application may facilitate generating an image of a source cloud block drive formatted according to a first format. the management application may facilitate copying of the image to a target cloud block drive formatted according to a second format. changes directed to the source drive during copying of the image may be stored to a first journal, which may be copied to the target drive. during copying of the first journal, changes directed to the source drive may be stored to one or more subsequent journals. upon determining that a subsequent journal is smaller than a configured cutover criterion, the management application may pause, during a cutover period, directing of changes to the source drive. the management application may copy changes, directed to the source drive during the cutover period, to the target drive and may redirect user/data applications to operate with respect to the target drive.
