Is it possible to export vCenter 5.5 data and import that data into vCSA 6.0?
I would like to move from the Windows based vCenter to the vCSA, but I would like to maintain the historical data.
I havent personally used it but this may get you going.

You may have to go to VCSA 5.5 first and then upgrade?
