Magento Upgrade Not Working

[eleanor_qeeple]

Hi Magento Support

we are currently revamping a site and we just bought a new magento theme. Tried to upload all the files and also upgraded magento from 1.5 to 1.9. While upgrading the magento the data from previous theme was lost and got an SQL error message which is : #1062 - Duplicate entry '677963-150' for key 'UNQ_BY_VISITOR'

Anyone here has this issue? Need help..

Thanks!
