1. If customer can not log in account, I think you miss to migrate magento customer password to 1.9. You can consider Magento migration password.

2. You can check Magento product information that are upgraded. Do you choose quality in upgrade magento 1.9? Or if you dont clear data on the target before moving data to 1.9, it can cause errors. Use Magento upgrade extension.
