** Is this an upgradeable version? **
There is no upgrade available from the older CalendarScript version 2, it is no longer supported by Matt (CalendarScript's author). You'd have to install the current version 3 from scratch.
** Does an upgrade need to be done from the same location? **
No, it can be installed anywhere as it won't use the original calendar's data. BTW. CalendarScript since version 3 is no longer freeware so be sure to read the pricing page for how much the registration fee will be for your particular usage.
