Users may assume that data updates can be performed from even a newly installed Zabbix Server 7.0 with Proxy 6.0(or other version of outdated proxies).
How about any additional tweaks or add any specific details for below document page such as, for example "outdated proxies are supported ONLY for receiving previously defined checks. This scenario it's only suggested during an upgrade limited period"
