Hello
baldredhead Welcome to the Ten Forums!
Cloning is generally seen with drives the same size or larger especially when going to shrink the OS primary cloned down a bit afterwards. You wouldn't be able to fit a 1.831tb size partition on the 500gb drive without a great deal of compression involved which would then slow the access time down. That would work in reverse of what you looking for to boost performance.
Your absolute best option would be to see an entirely new clean install of 10 go onto the smaller SSD drive and subsequently take advantage of the larger drive for storage and backup purposes once things are all set to go on the SSD. I run a piar of 2tb drives here for storage and backup and having just replaced a pair of 1tb drives find these two new drives are filling up fast too!
The clean install approach however is still your best option for taking advantage of not only the fresh Windows 10 install but what you are actually wanting to see the performance gain of running 10 on an SSD type drive.

If you are still running the upgrade over the previous version install of 10 but didn't download and save to ISO disk image form or burn a dvd if not see a USB Installation Key made up with the Media Creation Tool you can simply keep going back to download 10 to burn to dvd then to see it go on a flash and still save the "Windows.iso" to a folder to later needs.

Unfortunately 10 lacks the previously seen Windows Easy Transfer tool which made transferring files and settings onto a clean of Windows from an existing working install possible. But copy and paste manually of both program folders and user account sub folders for certain things can be done on the fresh install 10 before allowing the program installers to merge the new with the existing folders during the installation to pick up a good deal of where you left off on the 2tb drive.
If you run Steam games and wonder where all that 370gb of used drive space went following the 14-17gb of space a fresh install of 10 takes up look there! On the 7 side of the dual boot here that weighs in at 114gb while down a little to 110gb on the 10 side of the equation.
But as far as cloning or even making a full system image backup to restore onto the new drive you would need a second 2tb size drive to see any recommended working results. The encryption process may or may not end up being another problem depending on what program was used to clone or image a new drive with.
And once you have the clean install running on the SSD which is the advisement here you might want to consider seeing a "
Recovery Drive " made up with an 8gb or so usb flash drive since 10 and what to come will no longer see optical media type recovery images and tools. The Recovery Drive runs over 4gb in size. IF you ever have a time when not able to get 10 running and are not able to bring up the F8 boot options menu at post time/startup you would simply boot from the Recovery Drive where all of the repair options are seen.
