Duplicator vs All-in-One WP Migration

The two tools people weigh up when they need to move a WordPress site, built on opposite philosophies. All-in-One WP Migration is radical simplicity: export the whole site to one file, import it on the other end, done — URLs rewritten automatically. Duplicator is control: it packages the site into an archive plus an installer script, which is more flexible for staging, host moves, and developer workflows, but has a steeper learning curve. It comes down to how much you value simplicity versus flexibility.

// the picks

Best for simple one-click moves

All-in-One WP Migration

Export a single file, import it, and the URLs and paths are rewritten for you — the friendliest migration experience there is, on five million-plus sites. The pick for non-developers who just want the site somewhere else with the least friction. Watch the free import size limit on large sites.

Best for cloning & developer control

Duplicator

The archive-plus-installer model gives you fine control over rebuilding a site on any host, which suits staging, client handoffs, and repeatable deployments. Near a five-star rating on WordPress.org. The pick when migration is part of a real workflow, not a one-off.

// head to head

Duplicator

Backup · Free, Pro from $69 · Since 2011

Full review

Duplicator's signature move is bundling an entire WordPress site — files and database — into a single archive plus a lightweight installer.php, so you can drop it on any host and rebuild the site in a few clicks. That makes it a favorite for developers cloning sites, moving between hosts, or spinning up staging copies. The free version handles manual backups and migrations this way; Pro layers on scheduled automatic backups, direct cloud storage (Google Drive, Dropbox, OneDrive, S3), one-click restore, and multisite support. It carries one of the highest user ratings of any backup plugin on WordPress.org. Owned by Awesome Motive (Syed Balkhi).

Pros

The archive-plus-installer model is the cleanest way to clone or relocate a whole site
Excellent for developer workflows: staging, host migrations, local-to-live
One of the highest WordPress.org ratings in the category (near 5 stars)
Free version is genuinely capable for manual backup and migration

Cons

Scheduled backups and cloud storage are Pro-only — the free tier is manual
Renewals are billed at full price after a discounted first year
The installer-based restore is powerful but less beginner-friendly than a one-click UI
Very large sites can strain the packaging step on constrained shared hosting

All-in-One WP Migration

Backup · Free, Pro from $69 · Since 2014

Full review

All-in-One WP Migration is the go-to tool when you just want to move a WordPress site without thinking about it: click Export, download a single file containing the whole site (database, media, plugins, themes), then Import it on the destination — URLs and paths are rewritten automatically, no manual search-replace. That radical simplicity is why it sits on more than five million sites. The catch lives in one number: the free version caps the size of a file you can import (bounded by your host's upload limit), and lifting that cap is what the paid Unlimited Extension is for. Premium extensions also add direct cloud-storage destinations. Made by ServMask.

Pros

The simplest full-site migration experience available — genuinely one-click for non-developers
Automatic URL and path rewriting means no manual database search-replace
Enormous install base and a long, stable track record
Free export is unlimited; you can always get your site out

Cons

The free version's import size limit is the well-known catch — large sites hit it and need the paid Unlimited Extension
Backup is really a by-product of migration; it lacks scheduling and retention in the core plugin
Direct cloud-storage destinations require premium extensions
Restore means re-importing a full export, not granular file/database recovery

The verdict

For a straightforward 'move this site to a new host' with no fuss, All-in-One WP Migration is the simplest path — just mind the free version's import size cap, which large sites hit and which the paid Unlimited Extension removes. For staging environments, repeatable deployments, or any workflow where you want control over how the site is rebuilt, Duplicator's installer approach is more flexible and earns its slightly steeper learning curve. Simplicity versus control — and neither is a scheduled backup tool, so pair either with UpdraftPlus or BackWPup if you also need recurring backups.

Frequently asked questions

Is Duplicator or All-in-One WP Migration easier?: All-in-One WP Migration is easier for most people — export one file, import it, and it handles URL rewriting automatically, with almost nothing to configure. Duplicator's archive-and-installer flow is more powerful but asks you to run an installer and make more decisions, which suits developers more than first-timers.
Which handles large sites better?: Duplicator, generally — it's built to package large sites for rebuilding, without the import-side ceiling that trips up the free All-in-One WP Migration. All-in-One's free version caps import file size to your host's upload limit, so large sites need its paid Unlimited Extension. If you're moving a big site on the free tier, Duplicator avoids that specific wall.
Can either one schedule automatic backups?: Not in the way a backup-first plugin does. All-in-One WP Migration has no native scheduling. Duplicator adds scheduled cloud backups only in its Pro tier. If recurring, hands-off backups are your goal rather than one-time migration, pair either tool with UpdraftPlus or BackWPup, which are built for scheduling and retention.
