<div class="PlainText">You may be able to just copy the lfs_migrate script from a 2.12.x client, I don't think it has any dependencies on kernel or lfs features in the 2.12 release.<br>
<br>
I would of course recommend that you test it is working properly on some test hard-linked files before running it on the whole filesystem.<br>

we can't let them " be split into multiple separate files" by lfs_migrate as that would break things.<br>

or will I need a system wide outage to upgrade all clients and servers?<br>
