From the docs:

https://docs.oracle.com/en/database/oracle/oracle-database/21/upgrd/migrating-from-enterprise-to-standard-database.html#GUID-FD2DB65B-0E54-4ECE-8DF3-8E8F12FBD005

Converting from Enterprise Edition to Standard Edition requires exporting and importing data.

To properly convert from an Enterprise Edition database to a Standard Edition database, you must perform an Export/Import operation. Oracle recommends that you use the Standard Edition Export utility to export the data. If you only install Standard Edition software, then some data dictionary objects become invalid. These invalid objects create problems when maintaining the database.

The Export/Import operation does not introduce data dictionary objects specific to the Enterprise Edition, because the SYS schema objects are not exported. After the Import in the Standard Edition database, you are only required to drop user schemas related to Enterprise Edition features.

A correction ??

Hemant K Chitale, May 12, 2021 - 1:50 pm UTC

"you are only required to drop user schemas related to Enterprise Edition features."

Should it be "drop user schema *objects* related to Enterprise Edition feature" --- objects not entire schemas ?

(I tried to look for the option/button to provide feedback on the documentation page but couldn't find it)

The MOS not is referring to entire schemas (eg ORDSYS etc etc).

But I agree, we should really have a "change to SE" script that takes care of this in a safe manner for anyone doing this migration
