SkyKick vs Cloudiway: Migration Tool Comparison

You're scoping a Microsoft 365 migration and SkyKick and Cloudiway both keep coming up. They occupy the same general bracket — cloud-based, MSP-friendly, license per user — but they made very different bets about what an MSP actually wants. SkyKick bundles backup and onboarding tooling into a broader cloud-management suite. Cloudiway stays narrow and goes deep on migration source coverage. Picking the wrong one mid-project is expensive, so this is the engineer-level comparison.

The short version#

SkyKick is part product, part channel play. The migration tooling is solid, but the business is really about giving MSPs a single dashboard for migration, backup, security baselining, and cloud management. If you sell Microsoft 365 as a managed service and want one vendor relationship that covers the customer lifecycle, SkyKick is positioned for that.

Cloudiway is a French ISV focused entirely on migration. They cover more source platforms in more depth, particularly for the messy long-tail (Notes/Domino, GroupWise, Zimbra, HCL Verse, Google Workspace including Drive and Sites). If your projects involve genuinely heterogeneous source environments, Cloudiway is built for that.

Both run as SaaS. Both license per user. Both will integrate into an MSP practice. The differences below are where the picks diverge.

Source coverage#

This is the first filter for most decisions.

SkyKick supported sources#

SkyKick's supported sources lean toward what most SMB and mid-market projects actually have: Microsoft 365 tenants, Exchange on-premises (2010 and later), Google Workspace, generic IMAP, and PST files. Hosted Exchange providers and common SMB platforms are covered. Lotus Notes and GroupWise are not first-class citizens.

Cloudiway supported sources#

Cloudiway's source list is one of the widest in the market. Beyond Microsoft 365, Exchange, Google Workspace, IMAP, and PST, they also support Lotus Notes/Domino, GroupWise, Zimbra, HCL Verse, Kerio, IceWarp, and more. They also handle SharePoint, OneDrive, Google Drive, Google Sites, and Teams migration as separate but related modules.

Pricing and licensing#

Both vendors price per source mailbox, but the structure around it differs.

SkyKick sells migration licenses as part of a broader Pax8 or direct CSP relationship. List pricing per mailbox typically lands in a similar range to BitTitan and Cloudiway, but SkyKick partners get bundle pricing when Cloud Backup or other suite modules are part of the contract. The license includes Outlook profile reconfiguration tooling (Outlook Assistant), which is a real time-saver on larger projects.

Cloudiway sells migration licenses standalone. Pricing is published more openly than SkyKick's — you can usually get a list price from the website without a sales call. Licenses include unlimited passes within the project window, which matters because Cloudiway's incremental sync model tends to encourage multiple delta passes before the final cutover.

For one-off projects, Cloudiway is often the cheaper line item. For ongoing MSP practices where you also want backup and security baselining, the SkyKick bundle math sometimes works out better even at a higher per-mailbox sticker.

Throttling, concurrency, and performance#

Both products hit the same 429 TooManyRequests, ErrorServerBusy, and Microsoft Graph throttling ceilings on the destination side. Where they differ is the control surface you get.

Cloudiway exposes more granular tuning: per-endpoint thread count, per-mailbox concurrency, retry intervals, and explicit pause windows for business hours. This is useful when you're sharing the destination tenant with a backup product or another migration tool. It also means more knobs to get wrong if you don't know what you're doing.

SkyKick automates more of this. The platform monitors throttling responses and adjusts concurrency dynamically. You set a few high-level parameters (waves, batch sizes) and the platform decides the rest. For most MSP projects this is the right trade-off — fewer mistakes, less tuning time.

Expect 90–120 minutes per mailbox of average size (10–25 GB) on either platform when the destination tenant has clean throttling headroom. Both can run multiple mailboxes in parallel, so wall-clock time for a 200-user project usually fits inside a long weekend.

Outlook profile cutover#

Both products include an Outlook profile reconfiguration helper, which is one of the most painful manual steps on a migration without one.

• SkyKick Outlook Assistant: Runs on user workstations, reconfigures Outlook profiles after the mailbox is moved, handles OST rebuild gracefully.
• Cloudiway Endpoint Agent: Similar concept, available as part of the migration license. Less polished UI but functionally equivalent.

If you have 500 users to cut over without touching laptops manually, both products solve the problem. SkyKick's tooling feels slightly more refined; Cloudiway's gets the job done.

SharePoint, OneDrive, and Teams#

If your project scope extends beyond email, Cloudiway's coverage is broader.

Cloudiway sells SharePoint, OneDrive, Teams, and Google Drive migration as separate modules. The Teams migration handles channels, tabs, and (for many configurations) chat history with caveats around Microsoft's chat migration API limits. Google Drive migration preserves sharing permissions where the destination supports them.

SkyKick offers SharePoint and OneDrive migration but it's not as mature. Teams migration is supported but with more limitations on chat history and channel structure preservation.

If "and migrate the files and Teams too" is part of your scope, Cloudiway will probably cause less pain.

Backup and the broader suite#

This is SkyKick's structural advantage.

SkyKick Cloud Backup covers Exchange Online, SharePoint, OneDrive, and Teams. Buying SkyKick for migration means you can also offer ongoing backup to the same client without standing up a second vendor relationship. For MSPs building a recurring revenue book, that matters.

Cloudiway does not sell backup. It's a pure migration vendor. If you want backup, you'll need a separate product (Datto, Acronis, Veeam, etc.).

This is a genuine business model difference rather than a tooling weakness. Both approaches are defensible.

At-a-glance comparison#

Honest weaknesses#

SkyKick weaknesses. Source coverage is narrower than Cloudiway for legacy platforms. Pricing is partner-dependent and not always transparent until you're in a CSP conversation. The platform makes more decisions for you, which is helpful for SMB projects but sometimes frustrating when you actually want to control concurrency or retry behaviour. The push toward suite buying can feel forced if you only want migration.

Cloudiway weaknesses. UI feels engineering-driven rather than MSP-friendly — there's more to configure and more places to get it wrong. Support documentation is comprehensive but assumes Exchange and migration literacy. Reporting and customer-facing exports are functional but less polished than SkyKick's. No backup product, no security baselining, no broader suite — if you want one-vendor coverage of the customer lifecycle, this isn't it.

When to pick which#

The decision usually collapses around three questions.

1. What sources do you need to support?

• Microsoft, Exchange, Google Workspace mail, IMAP: either works
• Notes, GroupWise, Zimbra, HCL Verse: Cloudiway
• Heavy SharePoint, OneDrive, Teams, Google Drive content: Cloudiway

2. Do you want backup and broader cloud management from the same vendor?

• Yes, MSP suite story matters: SkyKick
• No, just migration: Cloudiway (usually cheaper line item)

3. How much tuning control do you want?

• "Let the platform decide": SkyKick
• "I want to set my own concurrency and retry intervals": Cloudiway

For broader context, the best email migration tools 2026 roundup places both in the wider market, and the best tools for MSPs guide goes deeper on operating both inside a managed services practice. The BitTitan vs CodeTwo comparison covers the other heavyweight pair in this segment.

When neither fits#

Both SkyKick and Cloudiway are sized for projects with at least a few dozen mailboxes, real budget, and proper change management. If your actual situation is "I need to move 6 IMAP mailboxes from one hosting provider to another by Tuesday", both products are too heavy and too expensive for the job.

That smaller bracket is what Mailbox Taxi covers. It runs locally on Windows, Mac, or Linux. There's no SaaS console, no per-mailbox license burn, and credentials stay on your machine. For IMAP-to-IMAP cutovers between providers like Gmail, Outlook, Yahoo, iCloud, Zoho, Fastmail, ProtonMail Bridge, and custom IMAP servers, it's usually the right shape of tool.

If your project is heavyweight Microsoft 365 work involving Notes, Teams, or backup bundling, pick between SkyKick and Cloudiway using the rules above. If it's closer to a clean IMAP cutover, Mailbox Taxi vs SkyKick and Mailbox Taxi vs Cloudiway cover the alternative.
