NOTE: Asset(s) for your academic unit's website should be uploaded to the academic unit's directory; asset(s) for faculty members should be uploaded to the faculty directory in the DAM.
Navigate to the location of the asset(s) that you want to replace.
Click Upload Assets in the Action bar
In the Open Dialog box, select the asset(s) you want to use to replace the one in the DAM.
NOTE: In order to successfully replace the asset(s), the new asset(s) must have the same file name as the one already in the DAM. With a different file name, AEM will assume you're just uploading new asset(s). NOTE 2: If you mistakenly upload an asset as a new asset instead of replacing an existing one, DO NOT delete the old one; by doing so you will also destroy all the reference links on the page(s) that is using the original asset.
