MDT file migration is incompatible with HSM

    Description

      Migrating a file between MDTs changes the FID of the file. The file FID is the used to identify the file in the HSM archive (unfortunately). So, for example, if a released file is migrated from one MDT to another then it cannot be restored.

            Reopening since lhsmtool_posix does not implement the discussed functionality.

            Please see LU-7207 for the proposed format for the external ID EA and including it in the delete changelog.
