Cloning my old spinning HD to small SSD after opencore

I have a nice late 2015 27" mac running OpenCore with sequoia. Works great! I would like a little more preformance out of the old girl by moving to a SSD drive. So far I have tried many canned methods to clone the drive, but no luck. I am thinking my issue is trying to clone a 1TB(with only 140gb used) and force into a 500gb drive. Thoughts or guidance would be appreciated. Thanks for your time.
