I don't have the 10gR2 installation notes in front of me at the moment, but I'm pretty sure you can go straight from 32 to 64 bit. -- Mark J.

Now I want to upgrade the 8i Database to 10g Release 2(64 bit). What will be the correct procedure. Do I need to upgrade firstly from 8i (32bit) to 8i (64bit) or I can go directly from 8i(32 Bit) to Oracle 10g Rel2 (64bit) Tx Sanjay ________________________________ Cheap Talk?
