Hi @ValerieAnders,
Switching to Adobe WebSDK for Target will mean you no longer need to manage at.js directly in your codebase. With WebSDK, Adobe keeps Target up-to-date automatically, so you’ll always be using the latest version of Target’s capabilities without needing manual updates.
Also, if you already have a datastream configured for your site or application, you do not need to configure a new one just for Target. With one production data stream, you can configure multiple Adobe tools. This is the advantage of WebSDK. One consolidated library for all experience cloud and platform products.
I hope this helps.
