Here’s an interesting, true-to-life story about the "All-in-One WP Migration 100GB Fix" — a saga of frustration, creativity, and a single line of code.
Instead of uploading through the browser, upload the .wpress file via FTP/SFTP to the backup folder:
.wpress file to:/wp-content/ai1wm-backups/ (create this folder if it doesn't exist)0644.Frustrated, Priya opened the plugin’s code. She wasn’t a developer, but she could read PHP.
She found the export class: class-ai1wm-export.php. There it was — a chunking system that split the archive into 10MB pieces to avoid memory bloat. Clever, but painfully slow.
Then she saw it: a filesize check in class-ai1wm-http.php:
if ( filesize( $file ) > 100 * 1024 * 1024 )
throw new Ai1wm_Error( 'File exceeds 100MB limit for chunked transfer.' );
A hardcoded 100MB limit per chunk before sending to the server. That explained everything. The plugin was designed to reject any chunk >100MB — but her archive’s metadata file alone was often 120MB after compression.
No wonder it failed.
