Link Guest Orders to Customer Account is a Magento 2 extension developed by PIT Solutions that automatically assigns guest orders to an existing customer account using the same email address during customer registration from both the frontend and backend. This powerful Magento ecommerce extension helps streamline order management and improves customer experience by ensuring all orders are properly linked. 

Features of this Magento e-commerce extension:

After installing and enabling the extension in store configuration, run the following CLI command from project root folder to associate previously placed guest orders with registered customer accounts. 
php bin/magento pits:link-guest-orders

This command will automatically: 

If your store contains more than 5000 customers, it is strongly recommended to execute the command in batches to avoid high memory usage and improve performance.

Use the start and end parameters to process customers within a specific Customer ID  range.

Example: 
php bin/magento pits:link-guest-orders --start=1 --end=5000

This command processes customers with Customer ID from 1 to 5000.

For the next batch, increment the range: 
php bin/magento pits:link-guest-orders --start=5001 --end=10000

A batch size of 5000 customers is considered a safe and stable value for most environments. 

Running Without Parameters

If the command is executed without the start and end options: 
php bin/magento pits:link-guest-orders

All customers will be processed without any limit. 
This is suitable for small to medium-sized stores but not recommended for large databases.
