Replaced HDD with SSD - How do I migrate the old HDD to the new SSD?

I have successfully completed the installation of a 2tb SSD replacing the original 1tb HDD. I thought I would be able to connect the HDD and simply restore to the new SSD but it doesn't want to work. I also thought I would be able to restore from Time Machine that I used on the old HDD but it doesn't even see the Time Machine backup when that drive is connected.

Can anyone instruct me on how I can migrate this old HDD to my new SSD with the new drive already installed? I don't want to break open the computer again, it was too intense the first time around.
