METHOD AND SYSTEM FOR PRESERVING FILES WITH MULTIPLE LINKS DURING SHADOW MIGRATION

A method for migrating files. The method includes receiving a first file system (FS) operation request for a target FS, making a first determination that migration for a source FS is not complete, and making a second determination that the first FS operation request specifies a directory and that the directory is un-migrated. In response to the first and second determination obtaining meta-data for content in the directory, and creating a directory entry (DE) for a first file in the directory on the target FS. The method further populating the DE for the first file on the target FS using file data, creating a DE for a second file in the directory on the target FS, linking the DE for the second file to the file data and the file level attribute, and servicing, after the linking, the first FS operation request using target FS.
