we have defined an agent group that contains more agents. Now we want to define 3 new agent groups in order to split these agents (with the correct agent mapping).
Are there any problems (data loss or something else)?
should we restart the agents?
Yes. The data will be lost in case of renaming the agents.
If you are adding more agent groups to distribute your agents in the same system profile then I guess there will be no data loss and of course you will have to restart the agents to map to the new agent group.
