We have a plan to make a copy of our PRD environment into our QA environment to get update data for testing by means of transporting the PRD DBF files over into our QA system.
However there is a discrepancy between the Oracle versions on both systems, on our PRD the Oracle database is 184.108.40.206 whereas in our QA environment Oracle database is newer at 220.127.116.11.
Would the QA environment having a more recent number be able to read DBF data files generated from an older version?
We will be moving all the control files along with the data files too.
Any advice from someone who've pulled such a stun before much appreciated :)
