I have 250GB of files in my onedrive personal and want to move them to my onedrive business, but i can't seem to find a function for this without having to download and then upload all the files manually. What do i do?
There is no action to move or copy OneDrive for personal to OneDrive for Business currently.
Before the last update, you could use List files in folder action to get all the files, including the files in the subfolders, and then use “Get file content-Create file” to move all files.
Just like the method mentioned in this thread:
But after this recent update, the List files in folder action has changed and it seems that we couldn't get the files in the subfolders.
So if your file directory structure is more than one layer, it is currently difficult to automatically move all files using Flow.
However, you could consider using OneDrive's own features to sync OneDrive for personal files locally, copy all the files, paste them into your local OneDrive for Business folder, and then sync all files to the OneDrive for Business cloud.
