Reply To: More clarity on "manually update"?

I’ll add to this if you don’t mind –

The other files he’s referring to is most likely your functions.php file. If you see any of the function names on the comparison list, then you’ll need to replace it with the new function/hook names……For some reason those links aren’t working, so we’ll have to find out where they went or add them to the new documentation section (coming soon).

If what you’re asking is can you keep the same css file and simply replace the old ID’s and Classes with the new ID’s and Classes presented in Genesis 2.0, then the answer is yes, thats what @kronos was referring to.
