Abstract
Disclosed herein are techniques for migrating data from a source memory range to a destination memory while data is being written into the source memory range. An apparatus includes a control logic configured to receive a request for data migration and initiate the data migration using a direct memory access (DMA) controller, while the source memory range continues to accept write operations. The apparatus also includes a tracking logic coupled to the control logic and configured to track write operations performed to the source memory range while data is being copied from the source memory range to the destination memory. The control logic is further configured to initiate copying data associated with the tracked write operations to the destination memory.
