Best Practice: Rolling Upgrades using DGPDB
Hello,
has anyone managed to perform a Rolling Upgrade between two 26ai (or 23ai), by using the DG on PDB Level. Or do I have to use the classic Dataguard in order to be able to use logical standby Databases.
Any recommandations how to be able to use the flexibility of the DGPDB and be able to do rolling upgrades?
Thanks in advance
