How difficult it is to move apps/files from one hackintosh SSD to another?

I am looking to upgrade my storage to a larger drive, upgrade my CPU and GPU. I am using Clover
for Catalina 10.15.1 right now with good luck but the features of OpenCore are really appealing and I'm thinking of using that on the new drive. My biggest question is,

How hard is it to move all my apps and files (akin to cloning the drive) from the smaller one to the new one? Ideally, I'd like to move all my apps files, etc. to the new drive so I can use the smaller one for another project.
