You would sort your users and apply quotas with filesets. You would use storage pools underneath filesets and the filesystem to migrate between faster and slower media. Migration between storage pools is done well by the policy engine with mmapplypolicy. Moving between filesets is entirely up to you, but the path names will change. Migration within a filesystem using storage pools preserves path names. <br><br> -- ddj<div>Dave Johnson</div></div><div><br>On Nov 1, 2017, at 6:55 AM, <a href="mailto:Matthias.Knigge@rohde-schwarz.com">Matthias.Knigge@rohde-schwarz.com</a> wrote:<br><br></div><blockquote type="cite"><div><font size="2" face="sans-serif">Hi at all,</font>

If it is possible the mmapplypolicy command could be useful.</font>
