I want to move as many folders and items as possible to a different document library within the same site, but I keep hitting road blocks.
When I use the "move" options in SPO, the process starts and takes a while, then says "finished/completed", but the folders and items are actually not moved. I assume it's because there are to many items in that folder (subfolder/items), but there is no way for me to know how many items that folder really has.
What options do I have to reliably move those folders? Is there a command line version that works more reliably?
