Transfer files from Dropbox to OneDrive
Server to server, without downloading anything to your computer.
How it works
Connect both accounts once. ShiftMyData then talks to Dropbox and OneDrive directly and streams the files between them in memory — nothing is written to our disks, and nothing travels down to your machine and back up again. The job runs on a worker, so closing the tab does not stop it.
Will every file be verified?
Dropbox offers Dropbox content hash and OneDrive offers QuickXorHash — no checksum in common. Files are compared on size and modification time instead, which is the same basis every other tool uses for this pair; nobody can do better, because the two providers do not share a hash to compare.
Before you start
- The largest single file OneDrive accepts is 250 GB. A bigger one is reported as failed and the rest of the transfer carries on.
- OneDrive refuses the characters " * : < > ? / \ | in a name, a name that starts or ends with a space, and names Windows reserves such as CON or desktop.ini. Such names are written with look-alike Unicode characters instead of failing, and turn back into the originals if the files are later copied out through ShiftMyData.
- A transfer copies each file's current content, name and modification time; sharing and version history stay behind on Dropbox. Business migration carries them where both sides support them.

Worth knowing about Dropbox
Dropbox uses its own block-based content hash rather than a standard one, so a checksum comparison works Dropbox-to-Dropbox and not otherwise.
Worth knowing about OneDrive
OneDrive's only checksum is QuickXorHash, which Microsoft invented and nobody else implements. It verifies perfectly against another OneDrive and is useless against anything else.
Steps
- On the Clouds screen, add Dropbox: sign in with Dropbox and allow access.
- Add OneDrive the same way: sign in with Microsoft and allow access.
- Pick the source folder in the left pane and the destination folder in the right.
- Choose a mode — copy, mirror, move, or two-way — and start the transfer.
- Leave it. Progress is on the Jobs screen, and a webhook can tell you when it ends.
Questions
Do I have to download my files from Dropbox first?
No. The transfer is streamed from Dropbox to OneDrive on our servers, so nothing is written to your machine and your home upload speed is not the limit.
What happens if I close my laptop?
The job keeps running. It is queued on a worker rather than in your browser, and the progress is there when you come back.
How do I know every file arrived?
Dropbox offers Dropbox content hash and OneDrive offers QuickXorHash — no checksum in common. Files are compared on size and modification time instead, which is the same basis every other tool uses for this pair; nobody can do better, because the two providers do not share a hash to compare.
Is there a size limit?
None imposed by us. What you move is drawn from your prepaid allowance (30 GB free, then 500 GB for ₹100 or 2,500 GB for ₹500, each valid a year). OneDrive takes single files up to 250 GB, and its own storage quota applies.
