Options available to for use:
- Oracle Database Migration Tool, need to go from 8i->9i and then 9i->10g
(need a 9i interim/staging database)
- Export data from 8i and import into 10g using exp/imp
- Database Links (Not complete what about views and stored procedures)
- SQL*Loader files (this would be very painful)
- There must something else which I did not use before (transportable
tablespace?)
My personal approach would be to use exp/imp since this does not require any
interim database and it will bring over all business logic contained in any
PL/SQL objects along with the data and other database structures (hint: only
export the schemas you want to migrate, not FULL=Y)
See matrix below:
Which EXPORT utility to use when importing into an Oracle8 or a higher
database release (always use IMPORT utility of the target database):
