As announced in the 2102 What’s New documentation , the old COPY and DISAGG operators are being deprecated and will be replaced by the Copy Operator (Advanced).
The “new” Copy Operator (Advanced) was introduced already with 2002 and has been improved very much since in regards to both functionality and performance.
As of 2105 customer will not be able to create new COPY and DISAGG operators anymore.
The best solution is that you migrate your operators yourselves using the mass import action in the Copy Operator Profiles app, instead of waiting for the automated mass conversion. This will provide you with more time to test and to reduce the risk. The mass import also offers a simulation mode
If you wait for the SAP-driven migration which is planned during upgrade to 2108, you at least need to check and correct inconsistent operators as described here: Preparing Automatic Migration plus page 19 of the pdf “Check and Correct Inconsistent COPY/ DISAGG Operators”
Independent of whether you migrate your operators yourself or wait for the SAP-driven migration, you do NOT need to adjust existing jobs or job templates.
