If you are testing locally or cannot purchase the extension, you can use server configurations or utility plugins like the Big File Uploads Plugin to sync your site’s internal variables. Ensure your server handles large streams by modifying these core settings:

: It bundles your themes, plugins, database, and media into a single compressed .wpress file Serialized Data Handling

Instead of moving a monolithic 100GB, consider moving only essential parts:

Once the progress bar reaches 100%, the site data is extracted, but you must complete these critical concluding steps to finalize the migration:

All-in-One WP Migration is a popular WordPress plugin designed to simplify the migration process. With its user-friendly interface and robust features, you can effortlessly transfer your website to a new host, domain, or server. The plugin supports exports up to 100GB, making it an ideal solution for large and complex websites.

: If you are comfortable editing code, you can sometimes manually adjust the plugin's constants.php file. By finding the line for AI1WM_MAX_FILE_SIZE , you can define a much larger limit in bytes. How to Perform a 100GB Migration

| Step | Time Estimate (100GB) | |------|----------------------| | Export | 30–90 minutes | | Transfer to remote server | 2–8 hours (depends on bandwidth) | | Import | 40–120 minutes |

, which removes all file size restrictions and supports multi-gigabyte transfers for a yearly fee. Legacy Workarounds

If you must transfer the file manually, do not use the WordPress admin upload dashboard. Instead:

Wait for the plugin to bundle the database, themes, plugins, and uploads into a single .wpress file. Do not close the browser tab during this compilation phase. Step 4: Importing the 100GB File Safely

Upload your massive 100GB .wpress file directly into this folder.

: Relying on a standard web browser to upload a single 100GB file via an HTTP portal will usually result in a failed connection half-way through the process. Phase 1: Securing the Unlimited Extension

: The official Unlimited Extension from ServMask removes all import size restrictions and is the recommended professional solution.

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 .

Moving an enterprise-level, asset-heavy site presents major logistical challenges. Standard shared hosting environments routinely drop connections long before a 100GB file can upload or process.

Randomly sample old and new images to ensure the 100GB media library structural integrity remains intact.

The core plugin restricts incoming browser-based uploads to 512MB. Attempting to drop a multi-gigabyte file results in an instant error prompt forcing an upgrade. Direct Comparison of Large Migration Strategies
