BIG IP DNS Upgrade questions
We are planning an upgrade of our BIG IP DNS cluster to 16.1.4 with the latest hotfix, we have already upgraded our LTM's to this version. I am following the upgrade guide of https://my.f5.com/manage/s/article/K11661449#verify-config-load and it seems pretty straight forward. One of my questions is the step referring to
"Update the big3d processUpdate the big3d process on all BIG-IP devices on all BIG-IP devices"
I am confused as if the DNS devices are upgraded won't they be running the same version? I have found other posts that they have waited until the entire upgrade is completed then they "install" the updated version. Any insight or clarification on this step would be greatly appreciated.
