Dear community

Can someone please explain me what Agent version i shoud use and what "best practice is" ?
My two Zabbix Servers are 6.0.14 and 6.0.0 so should i only use agent with the same version 6.0.xy or can i also use Agent with Version 6.4.1 or Zabbix agent 2 v6.2.9 ?

Thank you for your help

safest way is to use the same version as you server. Newer may contain modifications, which are not compatible with your server versions.
Classic or agent2, its your decision...
