Transfer files from OneDrive to Google Drive

Server to server, without downloading anything to your computer.

How it works

Connect both accounts once. ShiftMyData then talks to OneDrive and Google Drive 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?

OneDrive offers QuickXorHash and Google Drive offers MD5, SHA-1 and SHA-256 — 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 Google Drive accepts is 5 TB. A bigger one is reported as failed and the rest of the transfer carries on.
Google Drive accepts at most 750 GB of uploads per user per day. A 2 TB move into it takes at least 3 days however fast both sides are, so plan a large one as a daily schedule rather than a single run.
A transfer copies each file's current content, name and modification time; sharing and version history stay behind on OneDrive. Business migration carries them where both sides support them.

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.

Worth knowing about Google Drive

Google Docs, Sheets and Slides are not files in the ordinary sense -- they have no bytes to copy and no size until they are exported. ShiftMyData exports them to their Office equivalents on the way out; a native Doc cannot be preserved as a Doc anywhere except another Drive.

Steps

On the Clouds screen, add OneDrive: sign in with Microsoft and allow access.
Add Google Drive the same way: sign in with Google 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 OneDrive first?

No. The transfer is streamed from OneDrive to Google Drive 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?

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). Google Drive takes single files up to 5 TB, and its own storage quota applies.
