You can open an existing data feed that you created with the classic data feed editor and transfer it to the new editor.
Note that not all operators available in the previous feed editor are supported by the new data feed editor. When you open a data feed that contains an unsupported operator a corresponding message is displayed.
Procedure
The selected data feed opens in the new data feed editor.
The data feed is saved as a copy with the new name.
When you save the data feed for the first time, a copy of the data feed is created. You can now edit the data feed in the new editor. The original data feed remains unchanged.
