Migration wizard - not considering 12c feature

MuruganShanmugam

    I am migrating a database from SQL Server to Oracle and using latest SQL Developer tool (Version 18.1.0.095 & Build 095.1630). I have changed the preference to "Target 12c database". Regardless of , SQL Server feature like column identity which is also available in Oracle 12c is not implemented as column identity. Instead column identity in SQL Server is converted to a Sequence plus before insert trigger in Oracle which is bit painful in term of code maintenance. Am I missing something or is there any plans to implement this?

     

    Thanks
