摘要：
A Migration Thin Virtual File System (“MTVLS”) conducts file migration using a thin virtual layer that is size selectable and provides an uninterruptible migration path from the old file system to the new file system without an increase in the time to receive data. The MTVLS selects a file from the source file system, opens a corresponding file in the target system, mounts the thin virtual layer over the source file and the target file, and migrates that data from the source file to the target file.
