YDL 2.3 can i upgrade to 3.0 from within 2.3?

[Netzer Antonio]

7300/308mb ram, g3 upgrade card, ide controller card, 80 gig hard drive 
(3g for linux), ati 128xclaim vr, usb/firewire pci card.

i was able to install and run 2.3,
i've tried everything  to get 3.0 to install, but installer crashes 
upon choosing a partitioning method...
so i'm wondering if it's possible to do the upgrade within 2.3, which 
boots up fine...

thanks
