In case of backup files, when you move from a domain to another, you must
specify in the inclexcl parameter which mgmtclass you want to keep your
files. If you don't say nothing, all files will be sent to default mgmtclass
of that policyset.
In case of backup directories, they will be rebound to the mgmtclass of
longest duration, if you don't want that mgmtclass, you must set the
parameter dirmc in the dsm.sys.
In case of archive of files or directories you must have the same mgmtclass
in the other domain. If not they will be rebound to default mgmtclass.
