12c multitenant license
Hi,
As Oracle announced !9c can now support up to 3 PDBs without requiring additional multitenant license. We currently have some CDBs still on 12.2 with single PDB(we don't have multitenant license) and we're planning to upgrade them to 19c. During 19c upgrade testing we want to preserve some databases as PDB in other 12c databases.
I wonder if the 19c multitenant license change is retroactive to 12c or do we have to get the license in order to have multi PDBs in the 12c databases which will eventually get upgraded to 19c.
Thanks,
Hoa
