migrate my old hard drive to my new SDD drive with them both install in my desktop

hi is it possible to migrate my old hard drive to my new SDD drive with them both install in my desktop at the same time? also where can I download the software? I cant find any on SanDisk website Thanks

yes you can migrate with both the SSD and HDD connected internally to your desktop. SanDisk offers a one time use cloning software for free in the SSD Dashboard. Use the link below to install the SSD Dahboard and on the Tool tab there will be an option for Apricorn cloning software.

Thanks for that link. When Sandisk says “One Time”, how would it know that it’s not used multiple times already?

the software does a check and will only run one time. If the clone is sucessful the software locks out unless you purchase it to unlock it. 

Hope this can help you http://lifehacker.com/5837543/how-to-migrate-to-a-solid-state-drive-without-reinstalling-windows
