We are planning to upgrade oracle from 18. to oracle 19.
Database size now is more than 10TB, since downtime is quite critical for us,
therefore export and import is not possible, do you have any suggestions how we can achieve this and reduce downtime to minimum?
1. same hardware(Linux Redhat7)
2. DB: Oracle upgrade from 184.108.40.206 to 19 (maybe 19.8)
3. Downtime minimum
thanks a lot.
