Ansible AWX 17.0.1 upgrade on production server

Hello,

I have Ansible AWX 17.0.1 installed on production server RHEL7.
How can I upgrade it to higher version?

Only verified method please. I don’t want to ruin anything.
Such upgrade I should prepare to 17.1.0 version? Because I saw that starting from 18.0.0 K8S cluster is needed - is it correct?

Thank you in advance for your help!
