How To Move Your Lightroom catalog or Collection to Your new computer

Confusing…need to show all steps

This tutorial is pretty bad not gonna lie

This is not a clear tutorial, at least not for beginners

So much noise.

I have all my images in one disk and 3 lightroom apps. How do i consolidate them into the lightroom classic?

Do you have to do this for each folder you have? I see you have multiple folders but only selected one? I have about 20 folders ...do I just need to select them all and export?
