Upgrade configuration files directory is not found on node <node name>.
You selected a node that contains Repository Agent and PowerCenter Server configuration files to upgrade in the Upgrade Wizard. However, the server/upgrade/cfgfiles directory does not exist on the node. The directory was removed after installation.
Create the directory and place Repository Agent and PowerCenter Server configuration files in the appropriate global_repo, local_repo, and PCServer directories under the server/upgrade/cfgfiles directory on the node, and then validate the files again.
