How to remove agent 12.1.0.2 Home after upgrading to 12.1.0.3?

Hi

This is EM 12.1.0.3 on rhel 5 x86_64.  I upgraded all the 12.1.0.2 agents to 12.1.0.3 using the Agent Upgrade Console. The old AGENT_HOME was $AGENT_BASE/core/12.1.0.2, and the upgrade process added the new home as $AGENT_BASE/core/12.1.0.3.  EM recognizes the agents at the new version; only 12.1.0.3 agents are listed under Clean-up Agents.  EMCLI get_signoff_agents also returns just the 12.1.0.3 installed version for the agents. 

How do I remove the actual 12.1.0.2 software Home from the hosts?  I'd like the space back.

Thank you,
