Replacing current live rocks for new scape

[Peter luu]

Hi I was wondering if or how to replace all live rocks in tank for new Caribbean live rocks.
Wanting to order 40lbs of caribeansea live rock and rescape my live rocks as I want it off the back wall and less clutter.

here current shot of tank
There current 6x6x1” brick and 2 maxspect mini bricks ( 2 ) and 3lbs live rock in my sump.
I can add maybe another 4lbs of live rocks to help with bio.

what would I need to do to replace old rocks?

thanks

Don’t mind the 3 hammer corals on sand bed. Literally just added them 30mins ago and that’s when I decided I wanted to make a new rockscape
