All-in-One WP Migration 101: Features, Migration, and Troubleshooting Tips

Migrating your WordPress site raises valid concerns about data loss and potential downtime. Even with the popular All-in-One WP Migration plugin, fears of technical mishaps and doubts about effectiveness lead most users to postpone this crucial task.

But what if you could eliminate those worries with practical insights? 

We’ve tested this plugin firsthand and created a comprehensive review and guide that cuts through the confusion. By the end, you’ll have a clear understanding of what this migration plugin offers and the confidence to migrate your site successfully.

TL;DR: All-in-One WP Migration efficiently handles transfers for small to medium WordPress sites with a 512MB export and a 100MB hosting imposed import limit in the free version. For larger sites or easier moves, Migrate Guru offers a free, seamless alternative without size restrictions.

All-in-One WP Migration overview

All-in-One WP Migration takes a simple approach to WordPress transfers: pack everything into one .wpress file. During our testing, this proved both its strength and occasional weakness.

The plugin exports your complete site (content, themes, plugins, and database) into a single downloadable file. You then import this file to your new location. It’s remarkably direct, especially for beginners who might otherwise struggle with manual database transfers.

Here’s what works well:

Here’s where it falls short:

The plugin supports various migration scenarios: local-to-live transfers, hosting provider switches, and domain changes. Sites larger than 100MB will hit hosting-imposed upload limits.  You can either manually adjust your server settings or purchase the Unlimited Extension add-on to proceed.

For small to medium WordPress sites, it delivers on its promise of simplified migration. The interface is clean, the process is logical, and it removes much of the technical complexity that intimidates many users.

Feature analysis

Here’s our detailed breakdown of the plugin’s key features, performance benchmarks, and pricing structure to help you decide if it’s right for your migration needs:

1. Ease of use & workflow

The plugin’s interface is intuitive. Most non-technical users can initiate their first migration within 10 minutes without needing tutorials or guides.

Instead of a step-by-step wizard, you get two clear sections: Export and Import. These guide you through the process naturally. The drag-and-drop import feature handles the technical complexity, while progress bars show exactly what’s happening during transfers.

The result? A minimal learning curve. If you can upload a file to WordPress, you can handle this plugin.

2. Migration capabilities

Building on that ease of use, the plugin excels at comprehensive site transfers. It captures everything from content and media to themes, plugins, and database settings in one package. This eliminates the guesswork that plagues manual WordPress migrations.

The built-in Search and Replace function automatically updates old domain names to new ones during export. This prevents the broken links that often derail DIY migrations.

Migration scenarios supported:

You can exclude specific items during export. This includes spam comments, post revisions, or unused plugins. This targeted approach helps control backup size and saves time and storage space.

Premium extensions expand functionality:

3. Performance & scalability

We tested the migration with a 1GB site to understand its performance. Generating the export file took about a minute, creating a 191MB .wpress file.

The main bottleneck emerged during import. Sites above 100MB hit hosting-imposed restrictions. If you come across this block, you’ll need to manually increase your server’s upload limit or purchase the Unlimited Extension. 

Our 191MB file triggered this limitation, but once we fixed our upload limit, the import process took about 3 minutes to complete. 

Size considerations that impact usability:

Before making server changes, backup your site independently. While the plugin creates backups, having an additional backup provides extra security.

4. Compatibility

Performance concerns aside, the plugin’s compatibility coverage is comprehensive. It works across all hosting providers that support WordPress installations. It functions seamlessly on both Linux and Windows servers with various PHP versions.

No special server configurations are needed beyond standard WordPress requirements. Large sites might need server resource adjustments (PHP memory, execution time, upload size), but this reflects hosting limitations rather than plugin issues.

Universal compatibility is a clear strength, making the plugin accessible regardless of your hosting environment.

5. Pricing

The free version handles site exports up to 512MB with host-limited upload sizes for imports. This works for smaller sites but quickly becomes restrictive. Here are some add-ons All-in-One WP Migration offers:

Unlimited Extension ($69):

• Bypass PHP limits 
• No execution time or memory timeouts
• Server restore for backups of any size
• Tools for site management
• WP-CLI commands
• Use on unlimited sites

All-in-One WP Migration Pro ($99):

• Includes Unlimited Extension
• Automated backups
• 15+ cloud storage integrations
• WP-CLI support
• Tools for site management

Multisite Extension ($319):

• Includes Unlimited Extension
• Full network export in one click
• Selective subsite migration
• Subsite to single site conversion
• Import single sites into existing networks
• Clone subsites within networks
• Multi-network configuration support

For most users with substantial sites, the Unlimited Extension becomes essential if you want to continue using this plugin. Otherwise, you’ll need to consider alternative migration solutions.

Migrating your WordPress site

Moving your WordPress site doesn’t have to be complicated. Here’s how to use All-in-One WP Migration to transfer your site safely and efficiently.

Pre-migration Essentials

Before starting your migration, ensure you have these fundamentals in place:

1. Destination site setup: For the import to work, your destination WordPress site must be empty. The process will overwrite everything, so any existing content will be permanently lost.

2. Plugin installation: Install All-in-One WP Migration on both your source (old) and destination (new) sites.

3. Backup your source site: Create an additional backup of your old site using your host’s backup tool or a backup plugin. While the plugin creates a .wpress file, this separate backup serves as your safety net.

4. Check disk space. Verify sufficient space on:

• Your old site’s server (to create the .wpress export file)
• Your computer (to download the .wpress file)
• Your new site’s server (to upload and store the imported files)

5. Stable internet connection. Ensure a reliable connection throughout the migration process to avoid interruptions.

How to migrate your site using All-in-One WP Migration

Step 1: Export your site

• Navigate to your source site’s WordPress dashboard and click All-in-One WP Migration and then Export in the sidebar

• Choose your export settings under Advanced options if needed

• Select File as your export location (only free option available)

• Click Export and download the .wpress file to your computer

Step 2: Import to the destination site

• Similar to the export process, navigate to your new site’s WordPress dashboard and click All-in-One WP Migration and then Import in the sidebar

• Click the Import from button and select File

• Choose the .wpress file you downloaded and start the migration process

The import duration depends on your server and file size.

Important: After the import, the username and password for your new site will no longer be valid. You’ll need to use the login details from your old site instead, as the migration process replaces them.

Post-migration essentials

Use your old site’s username and password after the plugin logs you out.

1. Update permalinks: Once your site’s imported, you’ll need to refresh the permalink structure. Just head to Settings > Permalinks in your new dashboard and click Save Changes; no need to alter anything. This will ensure all your links are working correctly.

2. Clear all caches: After the migration, remember to clear all caches to ensure everything displays correctly. This means purging any caching plugins on your site, clearing your browser’s cache (usually by pressing Ctrl+F5 or Cmd+Shift+R), and, if your host offers it, clearing any server-level cache.

3. Test your site thoroughly: 

• Click through all pages and posts
• Verify that images and media load correctly
• Test forms and interactive elements
• Check redirects to the new domain
• Test admin login and logout functionality

4. Clean up (optional): Delete .wpress files from your server using the plugin or FTP to free up storage space.

Troubleshooting common issues that may arise

Migration issues are frustrating, but most have straightforward solutions. Here are the most common issues you’ll encounter and how to fix them:

Migration gets stuck or fails

If your All-in-One WP Migration process halts, the progress bar freezes, or you encounter timeout errors, it’s typically because your server has hit its time or memory limits. This issue is particularly common when migrating larger websites or operating on shared hosting environments.

Quick fixes:

• Increase PHP settings (max_execution_time and memory_limit)
• Verify sufficient server resources
• Temporarily disable other plugins during migration

Site looks broken after import

Your site loads, but images are missing, styling looks wrong, or links don’t work. This occurs when the plugin doesn’t properly update all file paths and URLs during the migration process.

Quick fixes:

• Clear all caches (plugins, server, browser)
• Resave permalinks in Settings > Permalinks
• Check that the URL replacement worked correctly during export

Blank page or internal server error (500)

Your site shows a completely blank page or the 500 error message instead of loading. This critical error usually means PHP ran out of memory or there’s a plugin/theme conflict on your new site.

Quick fixes:

• Increase PHP memory limit
• Manually disable plugins/themes via FTP
• Restore from your pre-migration backup

Login issues after migration

You can’t access your WordPress admin area with your usual credentials. This happens because the migration overwrites your new site’s user accounts with those from your old site.

Quick fixes:

• Use your source site’s username and password
• Clear browser cache and cookies
• Reset password using the Lost your password? Link

Best alternative for the All-in-One WP Migration plugin

If All-in-One WP Migration’s size limits or manual file handling feel restrictive, Migrate Guru offers a different approach that eliminates these common pain points.

Migrate Guru moves your site directly from one WordPress site to the other without downloading files to your computer. This eliminates the file size bottlenecks that frustrate All-in-One WP Migration users.

The entire migration process runs on BlogVault’s powerful servers, not yours. This means no server timeout errors or memory limit issues, which is a common problem with other migration plugins.

Key advantages:

• It’s free
• Handles sites up to 100GB without paid extensions
• Completely hands-off process. No file downloads or uploads
• Server-independent migration that bypasses hosting limitations
• Automatic URL updates during transfer

This approach works particularly well if you’re tired of dealing with file management or have hit size limitations with other migration tools.

Parting thoughts

All-in-One WP Migration is a highly effective, user-friendly tool for WordPress migrations and backups. While the free version’s size limit can be restrictive, the paid extension resolves this. 

Despite minor friction with its .wpress format and occasional server limits, it remains a powerful, user-friendly solution for confident WordPress site moves across all skill levels. 

However, for very large sites or those on restrictive shared hosting, Migrate Guru stands out as an excellent, free alternative due to its off-site processing and robust handling of massive transfers.

FAQs

Is all-in-one WP Migration free or paid?

All-in-One WP Migration offers a free version with a default import/upload size limit (512MB). To bypass this limit and unlock advanced features like cloud storage integration, multisite support, or direct URL imports, you need to purchase premium extensions, such as the Unlimited Extension or the Pro Bundle.

How to migrate a WP site manually?

Manually migrating a WordPress site involves several technical steps: exporting your database via phpMyAdmin, downloading all your WordPress files via FTP/SFTP, creating a new database on the destination server, uploading your files, importing the database, and finally editing the wp-config.php file to update database credentials and URLs. This method requires a good understanding of server environments and database management. Using a migration plugin would be a safer option.
