In which order can i upgrade multiple versions of zabbix and debian

[IteaAgain]

Hello,

i#m using zabbix 4.2 on debian 9
I would like to upgrade now to the latetest LTS version. Which seems zabbix 6.0 LTS and debian 12.

Are those versions compatible?

And what is the correct order of upgrading? Should i first upgrade zabbix or debian? Or did i need multiple steps (anyway debian needs to get upgraded version after version)?
