Cloning my OS drive

I am running Windows 7. I would like to upgrade to Windows 10 but my solid state C: drive only has 3 GB free so I am afraid I won't have room. I bought a new bigger solid state drive to replace my C: drive.
I ran a clone drive utility and now this is what it looks like:

Old drive:
C: OS
D: System Reserved

New drive
H: System Reserved
I: OS Clone

What I need to do is get I: to become C: and H: to become D: but I am not sure how to do that.

Do I just pull out both drives and plug the new drive into the location that the old drive was?

Do I need to to go into device manager and remove the new drive first?

I am not sure how to proceed here.

Any ideas?

Thanks.
