I tried to import a dump file (user level) Oracle 7.03.04 into a database 8.1.6 but it fails. The error message was
IMP-00010: not a valid export file, header failed verification
IMP-00000: Import terminated unsuccessfully.
The platforma is NT4.
Should I import it before to a database 7.03.04 and then migrate to 8.1.6.
Importing to a different version
According to the Oracle installation manual, if the database release is prior to release 126.96.36.199.6, migrate to at least release 188.8.131.52.6 before using the migration utility or the Oracle data migration assistant to migrate it to release 8.1.6.
