Full database export using expdp
If this is not the right thread, please let me know.
I am tasked with moving 12c databases on Solaris 11 to 19c on RHEL8. Following info provided in the Admin Guide, all "user-defined" tablespaces must be set to read only prior to export. I can find many places in blogs, Oracle documentation, etc telling me the tablespaces created by default (when you create a new database) are SYSTEM, SYSAUX, TEMP, UNDOTBS and USERS.
I created an empty container database on my target 19c installation in order to import my database. At creation, that new database contains SYSTEM, SYSAUX, TEMP, UNDOTBS and USERS.
