This is wrong, the procedure described in the README does _not_ involve
recalling all files. (I was mixing it up with an older release, thanks 
to Sheelagh who pointed me out.) Sorry for the confusion, I should read
the READMEs more thoroughly.

APAR IC22728 still is a problem, in case something goes wrong and the
file system has to be restored. Fortunately, there seems to be a
circumvention which worked for my test HSM file system: It is the procedure
described in the HSM manual under the topic "Restoring an Entire File
System - Backup Server and Migration Server are Different". This 
procedure involves restoring the directory structure (dsmc rest -dirsonly),
restoring the stub files (dsmmigundelete) and restoring the rest
(dsmc rest -replace=no).
