How to clone a 600 GB half-full drive to a 300 GB solid-state drive?

 I have a 600 GB hard drive on my Mac mini in my MacBook Pro that is using only 290 GB. Can I clone this to a 300 GB solid-state drive? My goal is to replace the boot spinning drive with an SSD drive. Then use the 600 GB HD as a second drive. 

Is there any possibility to clone the SSD if the drive is in a USB enclosure? Can I clone to the SSD if it is in a USB enclosure as well? Please tell me what is the best cloning software to do this task? 

OS: macOS Sierra

Yes, you can do that, however having so little space left on the solid state drive after cloning might be an issue when you start running the Mac computer. You can use either Disk Utility or Stellar Drive Clone Software to this task.  However, be very careful; make sure that you do not switch the source and target (you will lose all your precious files and folders. Try to find some tutorials on how to clone using Disk Utility and Stellar Drive Clone Software print them and make sure that you understand each step before proceeding with the cloning. Alternatively, if possible then try to purchase some external hard drive for creating a complete Time Machine backup of your local Mac HD. Now, replace it with the solid-state drive and restore from Time Machine. It would be slower, but you will have an extra copy of your complete data.
