When upgrading the SDA from 8 to 9, please copy the driver feed drivers from the old location to the new one?
We upgraded from a late version of 8 to 9.0.144. I found that none of the drivers in the old location (driverspostinstall\dell\windows10x64) were copied to the new location (Z:\driverspostinstall\windows\10\x64\any\dell).
I didn't find that out until yesterday while working with support to discover why driverfeed wasn't working for VMware machines (that's another issue).
