If customer is renamed the OOTB shipped DB indexes then while generating the DDL for upgrades generateDDL utility identifies that index does not exists and generated the respective create index statement.
So this will cause the index alredy exists issue while applying the generated schema. Plese ask customer to rename the indexes to OOTB index names and proceed with the upgrade.
