Hi,
Currently I'm running version 6.21 and I am thinking of doing the update shortly.
Can anyone foresee any issues. My main worry is that I have had to open ports just to deploy the agent and on some older OSs I have had to do a manual install. What I really don't want is to be manually updating the agent on 200 servers.
Will 6.22 see older versions of the agent correctly?
HELP! 
Regards,
David
