If you are experiencing any conflict, please clean uninstall the Intel® Data Migration Software from your computer until Windows no longer detect any remaining file related to this software, then install the software again from this link: Intel® Download Center - Have you drive connected via SATA directly for better results. We always recommend that you have a backup of your information saved somewhere to avoid any data loss. *Important to take into consideration that the size of the data you are migrating does not exceed the SSD size.
Alternatively, you can also use this third-party tool called Ease US todo Backup* as well: http://www.todo-backup.com/products/home/free-backup-software.htm

Very important to consider that the Intel® Data Migration Software will not backup only the partition you want. It will clone the drive as a whole.
