I am looking at upgrading a 5 node 22.214.171.1244 deployment. When I select Upgrade I get the following error about patch versions. Patch 2 is installed on all nodes. Patch 1 in installed on 4 of the 5 nodes. We had to rebuild one of the nodes and during the build process installed patch 2 but not patch 1. The patches are cumulative so doesn't seem like this difference should matter but apparently it does. Any advice?
I am not sure if there is a way to patch just one node in the deployment. If this is a PSN and you have other fallback nodes, I would de-register this from the deployment, patch it with the same version as others and add it back again.
