Cloud-to-cloud migration tools compared: which one fits your move

They all move files between providers. The real differences are price, privacy, and who each one is actually built for.

What "cloud-to-cloud" actually means

A cloud-to-cloud tool connects two accounts and moves the bytes directly between the providers' servers, so your laptop never becomes the middleman and your home bandwidth stays free. Every tool below does that core job. Where they part ways is cost model, what happens to your credentials and file contents, and whether they're aimed at one person or a whole company.

The tools at a glance

(Pricing and tiers shift constantly — treat this as an early-2026 snapshot, not gospel.)

rclone — maximum power, command-line cost

rclone is the open-source benchmark: free, 70+ providers, no data caps, and scriptable into automated pipelines no GUI can match. The catch is the catch you'd expect — there's no graphical interface, no scheduling wizard, no drag-and-drop. If you're a developer or sysadmin comfortable in a terminal, nothing beats it. If that's not you, it's the wrong tool. (Tip for big jobs: run rclone on a small cloud VM so transfers happen at data-center speeds instead of over your home line.)

MultCloud — the popular default

MultCloud is the most widely used option: 30+ providers, server-side transfers, a friendly web UI. The free tier gives 5 GB of transfer per month; paid plans remove the cap. Two limitations matter for this comparison: it does not migrate permissions, and it stores your OAuth authorization tokens on its own servers — meaning a third party holds standing access to your connected clouds.

Movebot — pay once, move once

Movebot is built for one-time migrations: pay-as-you-go around $0.75/GB, no subscription, strong throughput, and pre-migration scanning. It's a clean fit for a single mid-sized move where you don't want a recurring bill. It isn't built for ongoing sync.

CloudFuze — for teams that can't lose permissions

CloudFuze is the enterprise pick. It preserves permissions, version history, timestamps, and even inline comments, and it's SOC 2 Type 2 and ISO 27001 certified. Pricing is custom. For a personal move it's overkill; for a company-wide Google-to-Microsoft migration it's often the only thing that keeps your sharing model intact.

Whimsy — privacy-first, for humans not terminals

Whimsy targets the gap between "too technical" (rclone) and "hands your data to a middleman" (most of the web GUIs). It moves bytes directly between providers through their native APIs — file contents never round-trip through your laptop or our servers — reads only the metadata needed to do the move, and revokes access the moment you disconnect a cloud. Browser-direct transfers are live for Google Drive, Dropbox, and OneDrive, with a real file-manager UI rather than a config file. It's in free early access.

How to pick, by scenario

• Under ~100 GB, personal: any GUI tool works. Choose on privacy comfort, not features.
• Developer or automation pipeline: rclone, every time.
• One-off mid-size move, no subscription: Movebot.
• Company migration where permissions must survive: CloudFuze.
• Privacy-conscious and non-technical: Whimsy.

The thing all of them share

Whichever you pick, you're trusting a tool with access to both of your clouds — so the privacy model deserves as much weight as the feature list. And the reason cloud-to-cloud tools matter at all is that they make leaving a provider cheap, which is the real test of any cloud: read why switching cost is the metric that actually matters, or jump straight to the step-by-step Dropbox-to-Drive move.

Whimsy moves files between Google Drive, Dropbox, and OneDrive without ever touching their contents. Try it in early access.
