You placed a file in the global_repo, local_repo, or PCServer directory in the server/upgrade/cfgfiles directory on a node. However, you can only upgrade Repository Agent or PowerCenter configuration files with the .cfg extension. The Upgrade Wizard cannot validate or upgrade the file.
If the file is a Repository Agent or PowerCenter Server configuration file, rename the file with the correct extension. If the file is not a configuration file, remove the file from the upgrade directory or ignore the error.
