Migrator – Site Migration and Backup

外掛說明

Migrator packs your database and everything in wp-content into a single file you can download, keep as a backup, and restore, on the same site or on a brand-new install somewhere else. When you restore onto a different address, Migrator rewrites the old URLs and file paths to the new ones for you, so the site just works.

Everything happens on your own server. There is no account to create, no file size sold back to you, and nothing is ever sent to a third-party service. Because it is fully open, you can read exactly what it does: the source lives at github.com/wppoland/plogins-migrator, which is also where to file a bug or request a feature.

How it works

1. On the site you want to copy, create a backup. Migrator writes your database to a portable SQL dump and streams every file in wp-content into one archive next to it.
2. Download that archive (or, on a big site, build it from the command line, see below).
3. On the destination, the same site to roll back, or a fresh WordPress install to move to, restore the archive. Migrator imports the database, puts the files back, and rewrites the source site’s web address and paths to this one.

The address rewrite is safe for serialized data: Migrator walks the actual data structures rather than doing a blind text replace, so the byte-length counts PHP stores inside serialized options and meta stay correct and nothing breaks.

A few things worth knowing

Backups are written to a protected folder (wp-content/migrator-backups) that denies direct web access, and the in-browser download is served only to logged-in administrators through an authenticated handler, the files are never exposed at a guessable URL. Each item inside an archive carries a checksum, so a truncated or corrupted backup is caught before it is ever restored over a live site.

Restoring overwrites the destination database and files, that is the point of a restore, so it asks for confirmation and is limited to administrators. Migrator never overwrites its own plugin folder during a restore, so it cannot pull the rug out from under itself mid-import.

For large sites where a browser request would time out, every job also runs from WP-CLI, which has no timeout:

wp migrator export
wp migrator import path/to/backup.migrator

What’s included

• One-click backup of your database and all of wp-content into a single archive
• Restore to the same site, or migrate to a new host with automatic, serialization-safe URL and path rewriting
• Choose what to leave out: media, themes, plugins, cache, spam comments, post revisions, transients, WooCommerce sessions or Action Scheduler tables
• In-browser export with a progress bar and a direct download, resumable so large sites finish across multiple steps, plus drag-and-drop restore
• WP-CLI export and import commands for sites too large for the browser
• A safety snapshot of your database before every restore, rolled back automatically if anything fails
• Per-item checksums so a corrupt archive is detected, not restored
• Serialization-safe search and replace across the database, with a dry-run preview and a wp migrator replace command, to change a domain, URL or path safely
• Inspect any stored backup before you restore it: source URL, WordPress and PHP versions, table count, plus pre-restore checks for table prefix, disk space and writability
• Self-hosted: no account, no third-party service, nothing leaves your server

How Migrator compares

All six plugins named here back up and migrate WordPress. What separates them is what you get without paying, so the grid reads the free edition of each. Every entry was checked against vendor pricing pages and vendor documentation on 29 July 2026.

The columns, left to right: Migrator, AIO is All-in-One WP Migration, Dupl is Duplicator, WPvivid, Updraft is UpdraftPlus, WPMigr is WP Migrate. A cell reads yes if the free edition does it, paid if that vendor sells it in a paid tier or add-on, no if the vendor does not offer it at any price, part if only partly, and ? if the vendor does not say. A row of paid is a paywall, not a missing feature; no is the one that means the thing does not exist.

Where Migrator is ahead in free. No size limit beyond what your own server allows, and a database snapshot taken before every import and restored automatically if the restore fails. No other free tier here documents that rollback. The free edition is complete on its own terms: it backs up and migrates a whole site, by hand, with nothing held back and no account to create.

What PRO adds. Scheduling, cloud and FTP destinations, incremental backups, encrypted archives, recovery points, server-to-server transfer, Table Sync, multisite restore, deploying to an empty server, resetting a staging site to a clean install, and a white-label mode that puts an agency’s own name on the plugin. From 49 EUR per year.

All-in-One WP Migration

Exports to a single .wpress file, and its AES-256 password-protected export is in the free plugin, which is one thing Migrator keeps in PRO. The free export is bounded by your host’s PHP limits; lifting them is the Unlimited extension at $69/yr. Multisite is a separate add-on at $319/yr.

Duplicator

Builds a package plus an installer. The vendor publishes a 4 GB ceiling for the free edition, and 500 MB on the DupArchive engine. Scheduling, recovery points and importing start at $99/yr.

WPvivid

The strongest free tier here for automation: scheduled backups with one retention rule, Dropbox, Google Drive, S3, OneDrive, DO Spaces, FTP and SFTP as destinations, and server-to-server transfer with a migration key. Archives split at 200 MB. The vendor states databases cannot be backed up incrementally, encryption in Pro covers the database only, and table-level merging is sold as a separate product.

UpdraftPlus

Free scheduling from every 2 hours up to monthly, with Google Drive, Dropbox, S3, Rackspace, FTP, Swift and email as destinations. Archives split at 400 MB. Multisite, incremental file backups and database encryption are Premium, $70 to $399/yr excluding VAT.

WP Migrate

Lite exports a ZIP and does not import at all. Moving files between live sites, and push and pull, are paid, $49 to $219 for the first year. No tier offers a cloud or FTP destination.

Competitor prices are in USD, Migrator PRO is priced in EUR, and no conversion is implied. List prices and tier limits change without notice, so confirm on the vendor’s own page before you buy. Migrator itself is free under GPLv2 with no account to create; PRO is 49 to 149 EUR per year.

Plogins Migrator PRO

The free edition backs up and migrates your whole site by hand. Plogins Migrator PRO makes it run itself:

• Scheduled and incremental backups – daily or weekly with retention; incremental stores only the files that changed, and every archive still carries the whole database
• Cloud and off-site copies – S3, R2, Backblaze B2, Wasabi, FTP/SFTP, WebDAV, Dropbox and Google Drive
• Recovery points – one-click rollback to a known-good backup
• Encrypted backups – password-protected archives, decrypted on restore
• Server-to-server transfer – move a site between servers with no manual download
• Table sync – import chosen database tables from a backup into a live site and leave the rest alone
• Email notifications and activity log – a silent failure never slips by
• Multisite, network to network – back up and migrate a whole network with correct URL rewriting; pulling a single subsite out is a WP-CLI job
• Reset a site to a clean install – take a staging site back to fresh WordPress without reinstalling: a safety backup first, then the tables dropped, a clean install, and the address, title and administrator password put back. Single sites only, not networks
• White label – replace the menu name with your own, point the upgrade link elsewhere and hide the purchase prompt, so a client sees the tool under your brand

Everything in the free edition stays free and open. Plogins Migrator PRO starts at 49 EUR per year, billed in EUR.
