    DBUA or Emp/IMP

    Niazeed

      Hello Experts,

       

      Currently am moving from oracle 9.0.6.0 to 9.0.8.0 then to 11G.  Our third party vendor  claim that just doing an import from 9i to 11G will do. My claim is to use DBUA. I need to tell him why DBUA is a better approach as it is oracle supported way for upgrading database.

       

      His evil plan is to create a new 11G database and then import the dump obtained from the 9i database. He says as long as the data is there, there shouldn't be any issue.

       

      Then why did oracle create dbua????
