    Description

      Make migration for DoM files with LFS command. This is not working out-of-box for Data-on-MDT files because it is not enough just change layout, data should be moved as well.

      The OST-to-MDT and MDT-MDT migrations to be supported. Note that MDT-MDT migration might just be "cp + rename", since it will be the same.
