Best way to upgrade with extra SSD

I have a HP 6300 with Sierra. Tried to stay with it for as long as I can, but since I use Xcode, I want to bring it up to High Sierra.

I picked up a cheap 128 SSD and was wondering what the best way to keep the settings, kext, iMessage, setup etc from the Sierra install?

It's not vanilla, I used UniBeast, MultiBeast and KextBeast.

Any ideas or instructions would be very much appreciated! Thank you.
