Import Oracle - Error SYS.DBMS_REPCAT_MIG.PRE_IMPORT

Export executado com a opção FULL=Y, exporta também os objetos dos usuários SYS, SYSTEM e demais. Quando na importação usa-se o usuário SYSTEM, este tem como Synonym alguns itens que conflitam com o objeto original ... gerando os erros a seguir:

imp system@manager file=export.dmp ignore=y grants=n indexes=n log=imp.log full=n fromuser=prod touser=lab tables=(tb_he,tb_de) constraints=n compile=n

Solução após 1 semana de sofrimento: importar usando SYS as SYSDBA
