That message says that you are running a new Jenkins war file but using the service management system that was provided by an old Jenkins RPM installer. That usually means the upgrade was performed incorrectly.
When Jenkins is installed with rpm (or apt), it needs to be upgraded with rpm (or apt). Do not upgrade Jenkins by replacing the war file. That bypasses the rpm (or apt) upgrade process.
# yum upgrade jenkins
