Export-Import in HANA DB

Hi...

I am trying to perform an export-import of a HANA DB user instance at schema level including all objects and data.

Export and Import works very well except importing a schema which contains a synonym referred to other existing schema .

Command:

IMPORT "<bkup_schema>"."*" FROM '<bkp_location>' WITH RENAME SCHEMA <bkup_schema> TO <brand_new_schema>;

It gives below error :

"SAP DBTech JDBC: [2048]: column store error: table import failed:  [2003] An index already exists with the same name "

When trying to use "REPLACE" clause in the command the error changes as below:

SAP DBTech JDBC: [2048]: column store error: table import failed:  [30117] Binary import failed (cannot execute drop statement)

Has anybody faced this type of error before??
