Migrate a couple of 11.2.0.2.0 schemas to 12.1.0.2.3 PDB
I have a new 12.1.0.2.3 RAC Multitenant (Single Tenant) Database installed on new hardware. I want to migrate data from RAC 11.2.0.2.0 database to PDB. The documentation says that Oracle recommends to upgrade to 11.2.0.3 or later) so information about registered options and components is include in the export. What are registered options and components? How will not bring this information from 11.2.0.2.0 affect my 12.1.0.2.3 database?
