How to Use All-in-One WP Migration (Beginner's Guide) - SupportHost
To migrate a large WordPress site up to 100GB using All-in-One WP Migration, you typically need a version of the plugin that has been modified to bypass the standard 512 MB import limit. This is often achieved by using an older version (like v6.77) and manually editing the code to increase the file size threshold. Guide: Migrating Large WordPress Sites (Up to 100GB) 1. Export Your Website
Install the standard All-in-One WP Migration plugin from the WordPress repository on your original site. Navigate to All-in-One WP Migration > Export. Select Export To > File. Download the .wpress file once the process finishes. 2. Set Up the 100GB Import Version
The standard free version limits imports to 512 MB. To handle 100GB, you must use a modified version of the plugin on your new site:
Obtain the Plugin: Many community guides point to GitHub versions (like v6.77) or specific tutorials that provide a pre-modified .zip file. If you’d like, I can:
Install & Modify: If you have an older version (v6.7 to v6.77), you can manually increase the limit: Go to Plugins > Plugin File Editor. Select All-in-One WP Migration. Open the constants.php file. Search for AI1WM_MAX_FILE_SIZE.
Increase the value (e.g., adding * 20 or changing the base number) to reach your desired limit, like 100GB. 3. Import to the New Site On your destination site: Go to All-in-One WP Migration > Import.
Verify that the "Maximum upload file size" now shows 100 GB (or your custom value). Drag and drop your .wpress file into the box.
Click Proceed when prompted to overwrite the database and files.
A 100GB website usually consists of a large database (rare) and massive file assets (video, high-res images, logs, or backups) stored in wp-content/uploads.
| Step | Time Estimate (100GB) | |------|----------------------| | Export | 30–90 minutes | | Transfer to remote server | 2–8 hours (depends on bandwidth) | | Import | 40–120 minutes |
Before attempting the migration, verify the resources on the destination server (the new host). The server must have enough disk space (at least 100GB free + room for expansion) and properly configured PHP settings.
Recommended php.ini settings for 100GB sites:
upload_max_filesize = 120Gpost_max_size = 120Gmemory_limit = 1024M (or higher)max_execution_time = 3000max_input_time = 3000One of AIOWPM’s hidden gems is the built-in Find & Replace (during import). If you changed domains (e.g., oldsite.com to newsite.com), the plugin will scan and update every serialized string in the 100GB database burden. No other plugin does this reliably at this scale.
Yes, but with important caveats. While the plugin can handle 100GB, success depends on your server environment, hosting resources, and patience.
