cubase 6.5

im running 6.5 and always wanted to change the default location for the audio pool. i have multiple hard drives one is solid state so makes sense to have my programmes run of that and use a big terabite drive for storage of track data (audio). i have enquired on this before and at the time peoples response were why would you wana do that ? but at last the world has caught on.
will i have to update cubase ? if so to which version?
