Uninstall Database manually for Unicode Conversion

Hi Guys,

While performing a Unicode Conversion, during Export, Unistall and Import of Database, I would like to improve times for Database Creation since its 5TB

My goal is to delete SAP/DB Instance Non-Unicode but keeping Tablespaces and Datafiles Layout, in order to not recreate them when re-installing SAP/DB Instance Unicode

According to SAP Note 1260050 - UNIX:Deleting Oracle DB Instance Based on NW7.1 and Higher, the steps are the following.

drop user SAP<SCHEMA_ID> cascade;

drop tablespace <TABLESPACE_NAME> including contents;

Are this steps valid to delete a ABAP Database, and keeping Datafiles structures for when Installing Unicode SAP Instance?

Thanks!
