Has anyone attempted this? I have an HA solution that I would like to move to the new v12, as the improvements (such as the speedy EPM-Pro) are quite impressive. I am curious what the best way to do that would be.
- Taking one server offline, upgrading it and then bringing it back online, than repeating for the other node.
- Run the update on the active server and it will automatically propagate to the standby node.
