We are in the process of upgrading our site from Magento 1.5 to Magento 1.7. In doing so we used the Cart2Cart automated shopping cart migration system at http://www.shopping-cart-migration.com/ to migrate all of our orders from our old magento 1.5 to magento 1.7 site. However, when we do that, the order numbers do not completely match.
Our old order numbers on magento 1.5 the sequence of order numbers is 1300042600, 1300042601, 1300042602, 1300042603, etc. When we migrate these orders to our new Magento 1.7 site, the order numbers change to a sequence of 100042600, 100042601, 100042602, 100042603, etc. According to the support staff at Cart2Cart, they say it is because the first number is the store ID.
We need a experienced developer to do either:
1. Change the system so that when we re-migrate all of the data, it will migrate with the prefix 13000....
2. Change all of the the existing orders that are on the site from a sequence of 100042600, 100042601, 100042602, 100042603, etc to a sequence of 1300042600, 1300042601, 1300042602, 1300042603.
