Were migrating from an 8i to 9i (via export/import utility) and embracing the new undo tablespace functionality - in order to do this do we need to do anything to the objects that are in the RBS tablespace? or will the import utility automatically migrate them to the Undo tablespace?
The RBS or UNDO tablespace only holds temporary data used to ensure consistency for transactions. Thus you dont need to migrate anything to your new undo tablespace. Just create the undo tablespace and thats it.
