YEs, EEPC extension 6.2.1 is compatible with 6.1.3 EEPC agents.
Thanks for your information.
if i replace the extension and setup of 6.1.3 with 6.2.1 than whether it will create any inpact on my older policies, task or system.
Please let me know.
Replace all newer extensions and push 6.2.1 package will not impact on any APPLIED policy.
