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 126.96.36.199.0. The new server is running version 12c Release 188.8.131.52.0. 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?
Please be kind. I'm very familiar with Microsoft SQL Server but know practically nothing about Oracle.
