After migrating several thousand assets, I need to run DAM Update Asset on all of them. I need to modify the workflow to have one more purpose, which is to create a "versionDate" metadata property on each asset, and copy the Last Modified Date from the file to that property value. I'm not really sure where to start - the development seems straightforward but I just need to know what files I'm modifying and why.
First create a Workflow Process Step to perform operation like "versionDate" and etc...
Than Go to /libs/settings/workflow/models/dam/update_asset.html ,edit the workflow model ,add Process Step component and select your custom process step and save it.
