I'm upgrading from ASA7 to ASA9
an Index with blank name was allowed in ASA7, but It's no in ASA9
When I try to RENAME the index using

ALTER INDEX "" ON "DBA"."TABLENAME" RENAME TO "index_name";

It gives syntax error

I have many customers need to migrate to ASA9, so I need to automate the
process of upgrade (using batch file or any other way)
