Zabbix Server upgrade

[Aviad]

Hello,
i am upgrading my system from 5.2 to 5.4.9.
all my server have agent with version of 5.2, is it ok to run Zabbix server on 5.4 and work with zabbix agent2 that already exist on servers and running agent version 5.2 ?

documentation is your friend - but on the other hand I think 5.2 is not supported - so if there will be any security bug in agent you will not get fix on 5.2 - that.s why is better to use LTS with agents if possible ( if not I'd say you'll upgrade it at some point )
