Installing Vista 64 on top of XP 32

So i am currently running XP but i am getting Vista tomorrow which i will be using as my main OS and i want to know if i need to do anything else?

Is it better to have Vista on C:/ rather than D:/ if so how do i move XP onto the D:/ partition or doesn't it matter?

Will there be any compatibility issues with the two?

If i want to remove XP later how would i do this?

partitions really dont matter unless you are bad at remembering things like me(Sticky Notes FTW)

there shouldnt be any issues with each one and if you waant to remove XP erase the partition

Oh and a quick note Update to SP1 on vista

If you're intent on using the C: drive as your active partition for Vista, why not just upgrade XP to Vista rather than delete it. There's no known way to move an entire OS installation, or for the matter of fact: it's entire partition, to another one and expect it to work immediately; The MBR and P Tables will just laugh at it.

Afterwards, install XP to the desired drive.

Easy way is to just pop in the Vista install disc and select upgrade from the autorun menu.

The other way is to reserve an empty drive that will fit your stuff and move everything you think necessary to it from the C: drive. Then do a clean install with Vista and move it back. Note that some programs rely on registry keys to function, uninstalling the OS will remove those registry keys, thus rendering the program useless.

i remember reading that upgrading xp32 to vista 64 is not recommended. cnt remember why they said that but you that that its fine, u sure?
