[ovirt-users] Update Self-Hosted-Engine - Right Way?

Hello, i want to Update my oVirt as Self-Hosted-Engine on CentOS 7. The way i whould do is as follow and i want to know if this is the right recommended way. 1. shutdown all virtual machines (can i do this from GUI, or should it better be done inside the VMs?) 2. yum update "ovirt-engine-setup*" 3. yum update 4. engine-setup 5. follow questions and hope all is updated correct... Is that all or should i do some other stepps before or between this? thx Taste
