Transfer files from MEGA to Dropbox

Server to server, without downloading anything to your computer.

How it works

Connect both accounts once. ShiftMyData then talks to MEGA and Dropbox 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?

MEGA exposes no checksum through its API, so files are compared on size and modification time. That is a limit of MEGA rather than of the transfer, and it applies whichever tool you use.

Before you start

The largest single file Dropbox accepts is 350 GB. A bigger one is reported as failed and the rest of the transfer carries on.
MEGA treats Report.pdf and report.pdf as two files; Dropbox treats them as one. Where both exist in one folder, only one arrives, so rename one first.
MEGA allows two files with exactly the same name in one folder, and Dropbox does not. Only one of each such pair is copied; rename duplicates before you start if you need both.
A transfer copies each file's current content, name and modification time; sharing and version history stay behind on MEGA. Business migration carries them where both sides support them.

Worth knowing about MEGA

MEGA exposes no checksum through its API and rate-limits free accounts aggressively. Transfers are compared on size and modification time, and a large move from a free account will be throttled by MEGA rather than by us.

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.

Steps

On the Clouds screen, add MEGA: enter your MEGA email and password.
Add Dropbox the same way: sign in with Dropbox 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 MEGA first?

No. The transfer is streamed from MEGA to Dropbox 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.
