<div>I cannot speak for Redhat, but the RHEL release cycles are documented: <a href="https://access.redhat.com/support/policy/updates/errata#RHEL8_and_9_Life_Cycle">
https://access.redhat.com/support/policy/updates/errata#RHEL8_and_9_Life_Cycle</a>

<div>The rule of thumb for Scale is that a new RHEL minor release will likely be supported in the Scale release or PTF following the RHEL release. There might be exceptions dending on the timing of the release dates, possible problems found in testing, etc.</div>

Sorry, one more thing: while you can often upgrade from say 3.10.0-1160.92.1 to 3.10.0-1160.95.1, like the kind of upgrade you’d see within an RHEL point release — and you’ll often see an older version get updated to list support for those kinds of version
 increments — you should definitely expect to potentially need to upgrade GPFS if you’re going between RHEL point releases, like 8.7 to 8.8 — those ones that change from, say, 4.18.0-425.x to 4.18.0-477.x.

<div>Sometimes unsupported versions will work, but often times they will not, and if you have a support contract, that difference is sort of meaningless since you wouldn’t want to run an unsupported version anyway.<br>
