New device. How to transfer data?

I have a MyCloud device that is no longer being supported. Ive purchased a MyCloud Home 4TB device instead. How do I get the files from the old to the new easily? Thanks

You can use the “do more” button and then network import.

Thanks. Assume Im starting at the very beginning :). Do I have them both plugged into my network at the same time to do this?

Yes. You need both devices plugged into the router. Then on the web app select do more and then network import.
