Make sure you don't miss any public synonyms, public db links, or roles.
These will not be exported with a user-level export.
The 20Gig size should be ok for this method (exp/imp). Larger databases might need to use other methods already posted by others.

> Hi All,

> 3. Export the 2 schemas from the 8i server and split the dmp file to

> 4. Ftp the dump files over to the new server during off hours.
> 5. Import the dmp files to the new 9i database.
