I have an existing Oracle database on a server that I need to copy to a new server. The old server is running version 11g Release 220.127.116.11.0. The new server is running version 12c Release 18.104.22.168.0. I need to keep the current database online but create a duplicate of that database on the new server. Can anyone tell me how this is accomplished?
