Zabbix Server and Proxies migration from version 5.4 to 7

[dinto]

Hi everyone!
I have an environment with a zabbix 5.4 server.
In this environment I have 10 remote units with zabbix proxy in the same version.
I need to migrate the zabbix server version to version 7.
What would be the best way to migrate the server first and then the proxies?
Is there any problem with proxies temporarily staying on 5.4 so I can gradually migrate?

Best regards,
Dinto.

Proxies below 6.0 are unsupported: https://www.zabbix.com/documentation.../compatibility for server 7.x
