Moving Steinberg VSTs to external drive - mac

Hi, I’ve just put 2 Seagate 1TB SSDs in my MacBook Pro. I’m using Cubase 9 Pro.
I’ve moved all my 3rd party plugin libraries over from Native Instruments, Sound Dust and Spitfire Audio.

I’m now wondering how to go about moving Steinberg VST libraries? I guess Halion is the main thing I want to move.

Can anyone shed any light on where the files are located and how to link them back to the plug ins afterwards??

Thanks for any help!
