We have a Partner Developer Edition org which has environment hub. This was created a few years ago. We are in the process of upgrading our development practices to use SFDX and scratch orgs. The Partner Developer Org has environment hub but I do not see developer hubs.
Can I still use scratch orgs from SFDX ? If so, how ? If not, what is our alternative?
[I have seen Brian Miller's answer Ability to enable Dev Hub / Unlocked Packages for Partner Developer Edition Org but I do not know how to get a Partner Businsess Org .]
