Urgent: Moved Folders Now Gone from SharePoint Online after Migration
I just did a quick test of what I did over the weekend with smaller project folders and using the Drag and Drop. If I copy entire project folders, that all have the same subfolder structure, the data stays intact. I then created a new main folder and moved a subfolder from another project into and it moved fine. I then dragged and dropped subfolders into the document library then moved to another folder and the data remained intact, basically replicating exactly what I did on the weekend.
The only differences is I used the Microsoft SharePoint Migration Tool 2.1 to migrate the Project folder versus manual drag and drop and the folder sizes being much smaller (200mb versus 25+Gb).
The reason I do not use the Drag and Drop is
1) This way doesn't copy all files and gives errors but does not give a list of all the errors, and only a small window shows the errors, but it doesn't tell you which subfolder the file failed on etc etc. I've copied one main Project folder using the drag and drop and it would yield about 20 errors and doing the exact same folder using migration tool copies them all fine.
2) Migration tool maintains folder and file properties such as owner and last modified. Drag and drop gets all copied as new.
3) Migration tool can be setup with multiple tasks ie I can add multiple folders, sites and doc libraries and it'll just run.
