Anyone successfully clone internal boot drive?

I've watched a ton of youtube tutorials, read a bunch of forums. I get that you can't just copy because of the EFI partition. Wondering if anyone has come up with a solution?

I guess I made a rookie move. I "tested" a Sonoma install on a 256gb drive. Got everything flushed out. All the settings the way I want and all the programs I want installed and now I'm realizing that was a bad move. I should have just "tested" on a 2tb internal drive.

I am having great difficulty trying to clone this installation from the 256gb drive to the 2tb drive.

Any help would be greatly appreciated.

If I could code I would create a little piece of software to solve this. I wish.
