How can I upgrade from Oracle 8i to Oracle 11g?
I'd probably create a brand new instance of 11gR1, then create a full database export of your schemas in the 8 database, then import them into the 11g database. Upgrading from 8 to 11 wouldn't be very fun. You'll want to make sure your 8i hardware will even support the new 11g system. The number of processes, CPU, memory, IO demand of 11 compared to 8 may overwhelm your setup.
