MicrosoftMicrosoftI recently did a bunch of this when we reorganized about 100 channels into about 10. I was moving the content from those channels into folders under the new, "master" channels. Since I was also renaming the folders at the same time I used a different approach.
First I synced the Document Library (Running Win 10 Files On Demand Sync) and then I used Explorer to move the documents from their original location to the new one. I was worried that it would have to DL the files and then copy them, but it actually didn't The copying was extremely fast and easy.
