I have 2 related questions: does MX7 code convert to CF11 without much difficulty? is MX7 compatible with Oracle 12C?

We are are planning to migrate MX7 to CF11 and am trying to determine how much effort it will take.  In the meantime, we are currently using Oracle 10.2 but am getting pressure to migrate to Oracle 12C before we migrate to CF11.  Is this possible?

Thanks
