Migration 100gb | All-in-one Wp
Even with the right settings, 100GB migrations can fail. Here is how to troubleshoot:
1. The "Internal Server Error" (500) This usually happens because the server runs out of memory or the process times out.
2. Browser Timeout Sometimes the browser (Chrome/Safari) times out before the server does. all-in-one wp migration 100gb
3. The Database is Too Large If your database is 1GB+ and your site is 100GB, the database import might fail.
Trying to download a 100GB .wpress file to your local computer is impractical. Instead, push the export directly to the cloud. Even with the right settings, 100GB migrations can fail
Are there other ways to move 100GB? Yes. But they are painful.
| Method | Complexity | Downtime | Risk | Verdict | | :--- | :--- | :--- | :--- | :--- | | FTP + PhpMyAdmin | Extreme | Hours | High (Broken serialization) | Avoid | | cPanel Backup (Full) | Medium | 1 hour | Medium (Restore overwrites everything) | Risky | | rsync (SSH) | Very High | Zero | Low | Only for DevOps | | All-in-One WP Migration | Low | Zero | Low | Winner | With the Unlimited Extension enabled
Why AIOWPM wins for 100GB: It handles serialized data automatically. When you move a 100GB site that uses page builders (Elementor, WPBakery) or Advanced Custom Fields (ACF), standard backup tools break the PHP data strings. AIOWPM fixes them on the fly.
With the Unlimited Extension enabled, the post_max_size and upload_max_filesize PHP directives become irrelevant for AIOWMP because it uses a custom uploader that splits the import file into chunks.
| Error | Cause | Fix |
|-------|-------|-----|
| “Maximum execution time exceeded” | PHP timeout | Use CLI or split migration |
| “Post size exceeds allowed limit” | Web server limit | Increase client_max_body_size (Nginx) or LimitRequestBody (Apache) |
| “Insufficient disk space” | Decompression needs 2‑3x the file size | Free up space or move to larger drive |
| “Connection reset” | Network timeout between browser & server | Use CLI import instead of web interface |
| “The archive could not be extracted” | Corrupted file during upload | Re‑transfer the .wpress file via FTP (not browser upload) |
