CONTAP-49481: Unable to add nodes with earlier patch releases to existing clusters
Issue
Nodes unable to join the cluster due to missing capabilities between verisons:
::> cluster join -clusteripaddr XXX.XXX.XXX.XXX -node-name node01 -allow-mixed-version-join true
System checks .........
Error: command failed: The currently running image on this node lacks the
following capabilities which are installed on other nodes in the
cluster:
<ONTAP_capability_name>
This node must be upgraded to <ONTAP_VERSION> or a later release or the cluster
must be downgraded to the release version of this node.
Resolve the issue, then try the command again.
