How to Migrating 3tb database through export/import
Hi
We are in the process of migrating 12c database which is 3TB to 19c .
Question :
1. should we be doing full export and full import , or should we be doing only application schema.
2.Will there be an impact if we import only the schemas , will something be missed.
3. Apart from profiles and roles , do we need to create anything before hand.
4.Do we need to set any environment variables before exporting /importing to make the migration smooth /flawless .
5. What other ways can this process be made fast
My sample export /Import is like below . Kindly let me know if any changes
