Abstract
Disclosed herein are methods, systems, and processes to provide and maintain data consistency during reverse replication. It is determined that a migrate operation or a reverse replication operation has been requested. Upon determining that the migrate operation or the reverse replication operation has been requested, a resynchronization identifier is set in a dirty region log (DRL) associated with a computing device that is subject to the migrate operation or the reverse replication operation. In response to the operation being the reverse replication operation, a master boot record (MBR) sector of a boot disk associated with the computing device is overwritten.
