I've a Magento site v.1.4 with all Products, Customers, Sales & Orders data which needs to be transferred / copied to a new Magento installation v.1.7.1, Kindly note the following before your bid :
1. I've already imported Customer's data and all extension related data successfully.
2. Only Products, Categories, Sales & Orders data need to be imported
3. The old Magento installation isn't allowing export of Product CSV data due to server issue, so only database importing is the solution.
Only those developers who have earlier accomplished similar task earlier must bid. I need this task to be completed in 6-8 hours.
