<p><tt>Hi Juanma,</tt></p>
<p><tt>Yes, it is safe. We have done it several times. AFAIK it
doesn't actually change current data and metadata. Just states
that filesystem is using latest version, so new features can be
enabled. <br>
</tt></p>
<p><tt>It is something to take into consideration specially when
using multicluster, or mixing different gpfs versions, as these
could potentially prevent older nodes to be able to mount the
filesystems, but this doesn't seem to be your case. <br>
</tt></p>
<p><tt>Best regards,<br>
Sergi.</tt></p>

<div dir="ltr">Hi,
<div><br>
</div>
<div>Recently our group have migrated the Spectrum Scale from
4.2.3.9 to 5.0.3.0. According to the documentation to finish
and consolidate the migration we should also update the config
and the filesystems to the latest version with the commands
above. Our cluster is a single cluster and all the nodes have
the same version. My question is if we can update safely with
those commands without compromising the data and metadata.</div>

<div>Thanks Juanma</div>
