So you may Check your Unified Auditing Policies after upgrading to Oracle 19c as well.

Cloud Migrations: The New Kid on the Blog – DOHDATABASE.com

You may have realized that you will find mostly on-prem database upgrade and migration topics covered on my blog. Which doesn’t mean that you can’t use most of these techniques to migrate to the cloud either. But it’s really hard to write about everything in full detail. Hence, today I’d like to introduce you to Cloud Migrations: The New Kid on the Blog – DOHDATABASE.com. And no, I was never a fan of this American boyband from the 80s and 90s 😉

Thank you, Barcelona – I’ll be back soon :)

Still, the reason for my blog post is not football. But I’d like to say Thank you, Barcelona – I’ll be back soon 🙂

Database Migration from non-CDB to PDB – Migration with Data Pump

You may have realized that there are a few techniques missing describing how to do a Database Migration from non-CDB to PDB – Migration with Data Pump is one of them.
