Help changing silver to red

[JJH93]

Hi everyone! So I've never taken anyone from silver to dark brown with a hint of red. And I'm having a brain fart. Should I bleach the silver out and then pre-pig and put the brown/red on as usual? Or is there another way to do it? Thank you!

I'd pre-pig then apply my target shade.
