Dear All,

I am planning to upgrade my server from version Arcgis 9.3 to ArcGIS 10.1. I understand that I have to upgrade the OS to 64-bit, but I havent found any documentation which says that the hardware must be 64-bit?

Can anybody out there tell me if I have to request for a 64-bit hardware or not?
Will ArcGIS 10.1 work on 32-bit machine running 64-bit OS(windows)?
