Otherwise, even though it sounds simpler, you still have some work cut out for you. With the Advanced setup you have to do all of that work manually.

As said every 5 minutes DRS will calculate the sum of the resource entitlements of all virtual machines on a single host and divides that number by the capacity of the host: Remember that the outcome is the same.

Based on these consideration dwepdive cost-benefit-risk metric will be calculated and if this has an acceptable value the VM will be consider for migration.

In his role, he covers vSphere Lifecycle. What if you have multiple locations and you want to deepidve vCenter Server from a complete site failure?

When deploying VCHA try to use the Basic workflow when at all possible to make the solution easier to maintain and deploy.
