Hi All,

We are trying to setup SalesforceDX in our company and I am stucked with a very basic understanding of the SalesforceDX architecture.
So Far we have Developer Sandbox for every developer. But from now on, we wish to have one developer sandbox and developers must create scratch orgs from this Developer Sandbox and when developer is done testing on QA Sandbox, then the changes are pushed to the production org.

In my understanding, to create a sratch org, user needs to login with Devhub org which is the production org. Every developer then needs to login with production login first to create the scratch org and then push the changes to VCS? Is my understanding correct here? If Devhub is enabled, why cannot we create scratch org from the developer sandbox? Could somebody explain the architecture? I tried to understand from different blogs but didnt get any substantial answer.

Thanks. Dev
