Please use the engine to upgrade hosts, there's a command in webadmin interface for that.
I didn't think you could do this in a single-host hosted-engine system? In such a deployment the engine has nowhere to migrate to, so it requires shutting down the whole "data center" in order to upgrade the host. I didn't think that could be done via the engine?
Personally, I still need to upgrade from 4.1.9 / CentOS 7.4!
Single host self hosted engine will require more work. You'll need to put the host in global maintenance, turn off the engine, yum upgrade the host and reboot. Then get out of global maintenance and engine VM should get back up and running in a few minutes.
Yeah, this is how I've done it in the past.
I'm curious what the steps should be going from 4.1.9 / EL7.4 to 4.3.x / EL7.7? I am pretty sure I need some steps along the way (I doubt I can jump directly from 4.1.9 -> 4.3.x and 7.4 -> 7.7, right).
So should I jump from 7.4/4.1.9 to 7.6/4.2.8 and then from there to 7.7/4.3.6?
4.1 cluster level is still supported by 4.3 engine. So you can upgrade the engine from 7.4/4.1.9 to 7.6/4.2.8 and then to 7.7/4.3.6 while on the host side you can go straight to 4.3.6/7.7. Once done, please update cluster level to 4.3.
Thanks,
