How to replace Security Defaults with Conditional Policies?

Hi everyone.

I want to start setting up Conditional Policies for fine grained control. I understand that I need to disable Security Defaults and set up Conditional Policies.

Can someone tell me what policies I need to cover the same ground as Security Defaults?

Also, is P1 enough to replace Security Defaults?

Finally, let's say that Security Defaults were to change. Is there a way to get notified about this so I can update Conditional Policies?
