Curt and sprior,
We had experienced a system hickup when we rolled out the 7.5 udpate late night around 1am on 12th and broke the server-side records of the updates and that’s why they were seeing the errors .We fixed it, so now all should be correct and the 7.5.0 updates are going out smoothly.
Curt, yes the upgrade is to ME7.5 GA. You should be able to upgrade from 7.1.1 to 7.5 GA.
Let me know how things goes. Thank you for your patience.
