Allinone Wp Migration 100gb Fix May 2026

Priya shared her fix on a niche WordPress forum. Within a week, thousands of developers with 50GB+ sites found it.

The plugin authors later increased the default limit to 1GB in an update — but only after a GitHub issue with 300+ upvotes, all linking to Priya’s post.

To this day, you can find that original line of code in older versions, like a fossilized bug. And Priya? She still runs her magazine, but now she keeps a local backup script — just in case.

Moral of the story: Sometimes the “unlimited” plugin just means you need to find the one hidden constant and give it a bigger number.

Start the export. This may take hours. The plugin will create a single .wpress file.

If export fails: Your server cannot package 100GB. You must use command-line (WP-CLI) or manual methods.

| Size | Plugin Method | |------|---------------| | < 2GB | All-in-One WP Migration (works great) | | 2GB - 10GB | Plugin + manual file upload to ai1wm-backups/ | | 10GB - 50GB | WP-CLI method only | | 50GB - 100GB+ | Do NOT use this plugin. Use rsync + manual DB migration | allinone wp migration 100gb fix

The "100GB fix" exists in code, but physics (upload time, memory, PHP limits) makes it impractical. For 100GB, spend 30 minutes learning rsync and wp-cli – it will save you days of failed plugin imports.

Moving massive WordPress sites can be a headache, especially when the free version of All-in-One WP Migration hits you with its default upload limits. If you're looking for a "100GB fix" without the premium extension, here are the most effective workarounds. 1. The "Big File Uploads" Plugin Trick

The easiest, no-code way to bypass the limit is using the Big File Uploads plugin.

How it works: It uses "chunking" to upload large files in smaller pieces, which tricks the server into accepting massive backups.

Setup: Install the plugin, go to Settings > Big File Uploads, and manually enter your desired limit (e.g., 102400 MB for 100GB). 2. Downgrade & Code Patch (Version 6.77)

Later versions of the plugin patched the ability to easily edit file size limits in the code. Many developers revert to version 6.77 to apply a manual fix. | Error Message | Cause | The 100GB

Step 1: Download and install version 6.77 (available on sites like GitHub).

Step 2: Go to Plugins > Plugin File Editor and select All-in-One WP Migration.

Step 3: Open constants.php and find the line defining AI1WM_MAX_FILE_SIZE.

Step 4: Replace the existing value with a much higher one. For 100GB, use:define( 'AI1WM_MAX_FILE_SIZE', 100 * 1024 * 1024 * 1024 );. 3. The FTP "Restore" Bypass

If your server keeps timing out during the browser upload, bypass the "Import" screen entirely.

You need to remove the file size limitation in the plugin code. Moral of the story: Sometimes the “unlimited” plugin

Note: This change will be overwritten every time you update the plugin.

If you are determined to upload directly via the browser (not recommended for 100GB, but useful for files in the 2GB-10GB range), you must edit your server configuration.

You need to edit your php.ini file (access via cPanel, FTP, or ask your host).

Add or modify these lines to values higher than your file size:

upload_max_filesize = 120G
post_max_size = 120G
memory_limit = 512M
max_execution_time = 3000
max_input_time = 3000

Note: Many shared hosting providers (like Bluehost, GoDaddy, etc.) will not allow you to override these settings manually. You may need to contact their support and ask them to increase the limits for you.
