Hi there,
Does anyone know if I can move my MediaBay settings/preferences/indexes from Cubase 6.5 to Cubase 7 so that I don’t have to re-scan/re-analyze all my sample libraries? Obviously this would be a huge help to me as I can’t afford to spend a day re-scanning all my folders!
It did mine as part of the upgrade, no scanning just a straight copy i assume
Unfortunately, not for me. I made sure not to uninstall Cubase 6.5 before I installed Cubase 7, just in case – and now I have to re-scan all my folders 
Try something like this (I have an italian version of Cubase, some terms may change)
Open Cubase 6, then open Mediabay, and right Click over the desired disk -> Create disk database
Close Cubase 6
Open Cubase 7 -> Mediabay -> Right click on desired disk -> Import disk database
I hope this will help
