9i Migration to 11g

Question

Morning all,
We are contemplating a move from 9i to 11g when 11gR2 comes out. It was my understanding that there was a specific course being developed for just this topic.
has anyone done a migration to 11g from 9i and if so, can you give me the high points of the process.
Did you have to do an import export? manual or use the DBUA gui?
any insight would be great.
Thanks.
Can e-mail your responses if you like to [email protected]

Before you are going for the upgrade I would advise you to use the pre-upgrade information tool, which is basically an SQL script.

It will generate similar outputs as shown below;
