Upgrade way to 11g is good only by big databases.
After Oracle upgrade there are many errors, incompatible spfile parameters and so on (up to logical corrupted records and not working statistics).
So if your DB are not big I will recommend to make 11g installation from scratch.
But if your DB is big, or there is no experience, or the upgrade window is too small the the previous post is very good to help you.
Good Luck!
