In cae you have correct type and number of licenses - you not have licensing violation
I have 2 Old Servers, each with 2 Processor/4C running oracle Database Standard Edition License). This license renewable every year.
The new server I purchased have 2 Processors/8C. I intended to installed Windows Server 2016 Hyper-V to create 2 Servers to replace the 2 old server.
