Andreas - In those circumstances I would consider doing a final backup of
          the HSM file system(s), then do an EXPort Node of the backup
FILESpace.  On the receiving TSM server, do an IMport Node to plant the backup
storage pool, define the HSM file system and HSM storage pool at the new site,
and then do a full restore with -SUbdir=yes and -RESToremigstate=Yes (which is
the default) to recreate the directory structure, restore small files, and
regenerate stub files in the new file system.  (Note that RESToremigstate
restores only the ADSM record portion of the stub files, and thus you will see
the stub files have a length of 511 rather than 4096, indicative of there
being no beginning of the file data in the stub.)

This procedure basically follows the steps you would take to recover an HSM
file system.  Refer to the HSM manual and the HSM redbook for further detail.

Another approach might be to perform a cross-site restore to populate the HSM
file system at the new site, via dsmc restore -VIRTUALNodename=_________,
say over a 3-day holiday weekend or the like.  The relatively slow datacomm
link speed works to your advantage in giving HSM time to do dsmreconcile and
migration out of the file system to make room for the incoming populace.
