Transfer Relevant Database Tables: Identify the essential mod_lti tables that handle core LTI configuration. Move these specific tables into the new "core_lti" subsystem. Use the XLMDB tool accessible through Moodle's Site Administration > Development options to generate and execute the necessary migration code.

Selective Table Migration: Not all tables from mod_lti need to be moved across. Focus solely on the tables associated with core LTI configuration. For instance, the PREFIX_lti table, responsible for activity instance data, will remain within the mod_lti context.
