Upgrade Oracle RAC to version 19c - runcluvfy not passed because of missing patches - but they are applied!

Good morning all, I hope anyone can help me with this. I am trying to upgrade an Oracle RAC of two nodes from version 12.2 to 19c. As part of the prerequirements, I have applied the patch 28553832 in both nodes. Opatch and Kfod show both the same patches applied to both nodes Node 1 $crsctl query crs activeversion -f Oracle Clusterware active version on the cluster is [12.2.0.1.0]. The cluster upgrade state is [NORMAL]. The cluster active patch level is . $crsctl query crs softwarepatch Oracle Clusterware patch level on node scglvdoraci0010 is . $crsctl query crs releasepatch Oracle Clusterware release patch level is and the complete list of patches [26839277 27105253 27128906 27144050 28553832 ] have been applied on the local node. $ kfod op=patches --------------- List of Patches =============== 26839277 27105253 27128906 27144050 28553832 $ kfod op=patchlvl ------------------- Current Patch level =================== 1205374555 Node 2 $crsctl query crs activeversion -f Oracle Clusterware active version on the cluster is [12.2.0.1.0].

Would anyone in this scenario try to upgrade when the requirements are not passed ? Thank you
