Hello everyone, I just wanted to let you know that, as of today, the package structure I tried to set up above does not fully work on Upmind.
Yesterday, I talked to their support team, and discovered you can't provision two Enhance packages when you order one Upmind product. The bundle functionality of Upmind isn't automated yet, so I can't use it. same for attributes.
Currently, 1 Upmind package equals 1 Enhance package. You can't provision staging sites on a separate server.
