To be more explicit, the command is FILEPOOL UNLOAD. From a SFS administrator id, assuming "JOEUSER" is the file space you w ant to move, access the 193 disk and issue - FILEDEF UNLOAD DISK JOEUSER UNLOAD <fm> where <fm> is large enough to
contain the file space - FILEPOOL UNLOAD FILESPACE JOEUSER VMSYSU And then on the 5.3 system: - FILEDEF RELOAD DISK JOEUSER UNLOAD <fm> - FILEPOOL RELOAD FILESPACE JOEUSER VMSYSU HELP SFSADMIN FILEPOOL for more notes. Sue
