Connection from 12c to 9i

Hello ,

Recently I have upgraded one of my database from 9i to 12c.

I'm trying to connect oracle Oracle9i Release - Production from 12c Release - 64bit ,but I got message

ORA-03134: Connections to this server version are no longer supported

I can connect 9i to 12c by setting parameter in sqlnet.ora,  SQLNET.ALLOWED_LOGON_VERSION=8 , but I cannot connect 12c to 9i.

Any solution for 12c to 9i connection or any alternate solution will also appreciable.

Thanks ,
