Old agents do not install/report on EC Console

Old agents do not install/report on EC Console

Hi team,

I have noticed that when an old EC agent is installed on a machine,the agent doesnt report fine on the console.
But instead is shown at "Yet to Install"
Is there a way to install even an old agent and once it communicates with the EC,it can be updated automatically?
Even when i try to reinstall it from console, i get the following
"Agent needs to be upgraded. Uninstall the Agent and install again."

Best Regards,
Bionid
