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

I stopped more or less watching Champions League football since it is available on pay TV only for over a year in Germany. But of course I saw the result yesterday: Barca lifting Dortmund into the play-off stage by beating Inter in Milano. Well, I guess, all BVB fans will have celebrated yesterday night. Still, the reason for my blog post is not football. But I’d like to say Thank you, Barcelona – I’ll be back soon πŸ™‚

On Monday, Dec 9, 2019, I held a full day upgrade workshop in Barcelona. The Oracle ACS team did all …

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

And it allows you to move even from very old versions directly into an Oracle 19c PDB – regardless of patch levels or source and destination platform.

Database Migration from non-CDB to PDB – Clone via NON$CDB, upgrade, convert

The third option for plugging in a non-CDB is called Database Migration from non-CDB to PDB – Clone via NON$CDB, upgrade, convert. As I showed already in this blog post a while ago, your source must be at least an Oracle 12.1 database. And this technique can be used also only for same-Endianness migrations but does not apply if you’d like to migrate from Big to Little Endian. If your source database matches already the receiving CDB, no upgrade is necessary.
