Oracle Database Discussions

Hi everyone, I'm working on an internship assignment related to data migrations. I'm researching the best oracle software tool to perform a data migration. Someone suggested me to research the tool 'Oracle Data Migrator', but I cannot find anything about it on the internet. Google would normally redirect me to the homepage of the specific tool after a search, but the first few hits are related to small forums. Does the Oracle Data Migrator tool even exists?

thx
