Upgrade 9.2.0.4 standalone OID to iAS 10g

Has anyone done this?  Following the instructions in http://tinyurl.com/5g8vj
yields results that don't look like an upgrade.  Running the
Management Repository Configuration Assistant to install the
repository in an existing database results in a message that the ODS
user that exists must be dropped to continue--but the ODS user
contains all of my OID data.  Oracle Support has not been too helpful,
so any suggestions gratefully accepted.
