Database Upgradation from 8.1.7 to 18.104.22.168
Our client is planning to migrate their OLTP application from Oracle 8.1.7
to O9iR2. The current database size is 750 GB.
What is the best method to upgrade the database ?
1. Export/Import full database dump.
2. Coping all the 8i control files, data files and creating 9i database on
new box using the existing files.
