Migrating an enterprise WooCommerce catalog with tens of thousands of variable products, custom attributes, high-resolution media galleries, and taxonomy relationships is one of the most demanding tasks in WordPress engineering.
Standard import plugins collapse under memory exhaustion and PHP max_execution_time limits. In this guide, we break down how to configure WP Import Export Pro to execute a zero-timeout migration using asynchronous micro-batching, object cache flushing, and automated image processing.
1. The Problem with Large WooCommerce Imports
When a server processes a large CSV, PHP keeps objects in memory. Without memory recycling, importing 10,000 products quickly exceeds standard 256MB or 512MB limits.
2. The WP Import Export Micro-Batch Solution
By chunking queries into micro-batches of 25 records and executing them asynchronously, WP Import Export Pro processes 50,000+ items continuously without ever dropping the server connection.
