Hi Everyone
I had 160 Tb Database in 12.2 and had to upgrade to 19c. Can you please suggest the best option that can help to update with small downtime and also option to rollback for any failure without going for big Restore that can take day for the restore. Some details for the database and option that can be used are
- 12.2 is CDB with one PDB that has to be upgraded
- ASM storage has additional 200 Tb available to be used for this upgrade purpose ,if required for any option
- It is Exadata with two node
- Environment also has Dataguard on another Data Center with same hardware like primary
- Golden Gate license is available for any option that can save downtime Thanks for your time and suggestion Sanjay -- http://www.freelists.org/webpage/oracle-l
