Zabbix 3 random question

Hi

From the rc1 if you were to play around until production came out could you upgrade from the rc to prod or will it require fresh install

I recommended a clean install.

rc1 is just a release candidate.
rc version might be changed yet.
If you need a stable environment, it is better not to the version up from rc version.
