I have a requirement where I need to move 2600 assets from Production to lower environment and after running some test I need to export these assets back to production. These assets are scattered in different sub-folders across dam. Please could you suggest some way to achieve this. I am using Aem 6.4.8.
you can create a package using filter, the list you can extract from prod and create a package in local with the filter of all the assets file, once done upload a package in prod and build. there you will have the package and upload in lower env, once you are done with lower env changes then again build and upload & install in PROD.
