Schema name change after DB2 system Copy with Restore Method

Hi guys

Performing a System Copy with updated SAPINST for R/3 based on 640 systems using method Backup/Restore we are facing an issue with DB2 Schema.

The original system is P01, schema sapr3, SAP Version is 47x200, and DB2 v8.2

The target system is also P01, and with DB v9.7

How can the schema can be converted from sapr3 to sapp01 using Backup/Restore?
