Migrating ORACLE OBIEE Reporting to Work on Top of Teradata 13.10

We are looking to create an estimate for migrating an ORACLE installation to Teradata.  In this process, there are nearly 100 reports in OBIEE which must be migrated to run against the Teradata database.  Since we on this team have not done this before, anyone with some experience with the gotchas as well as tips for the estimating the costs would be of large benefit to us.  ORACLE 11g OBIEE is the version.
