I have added new web rendition property to the out of the box workflow and now i would like to run the workflow on all the assets existing on my machine.
Please suggest how to do it in best way.
In AEM 6.4,
1. Go to Tools ->workflows -> Models
2. Select DAM Update Asset - > From top, slect Start Workflow
3. Select the payload and you are done.
Additionally you can also refer to the official document to apply a workflow on multiple assets
