Migrating store information to Magento is a complicated and time-consuming process. It can take much time, efforts, require high tech skills and cost lots of money. There are several methods, but never of them is easy for online merchants and each of them causes data loss at some point. Now you can use Cart2Cart and migrate your store information easily and withing limited time period. Cart2Cart shopping cart migration service will help you to move your store data, saving the relationships between entities (categories, products, customers, orders etc). Supported versions: 1.1.x - 1.5.x Community Edition, Professional Edition, 1.6.x Enterprise Edition.

When the migration process is completed all registered customers will have to use password recovery form on the target shopping cart to use their profiles, due to the fact that various shopping carts use different password encryption algorithm..

Using this service. I was able to migrate all my clients orders and customers info from 1.3.2.4 to Magento 1.5.0.1. I  without any problems. However this tool can not be used to import magento grouped products into Magento,  if you try to import grouped products, Cart2Cart  will  convert them to simple products.
