Funny thing was when I went there it seemed to me to have copies of 3.0 and 4.0 but NO 5.0 for some reason.... not even in the rollback options for folks doing 6.0 updates... you could click on rollback for the other two even old versions but not that last one, 5.0 It seemed sort of weird to me too but that is what I saw..
From my understanding the changes between v5 and v6 are such that there is no clean roll-back.
If you want to see your data on one of the v6 platform, we are in-between provisioning flights and I have an instance that you could see your data on v6 if you are so inclined.
