Because /usr is continually in use, boot using a livecd of your choice.
In that environment, use fdisk (or whichever *disk you like) to make any
changes to partitions you know you will need.

Mount your gentoo / somewhere convenient
Mount your gentoo /usr somewhere convenient

copy the latter over to the former
edit fstab
reboot

It really is just a case of moving a large number of files around, but
because those very files are always in use you have to do it in livecd
environment.

There's no exact checklist one can follow to guarantee a 100% result
blindly. Instead, as this is Gentoo, we assume users built their system
knowing what they were doing and can appropriately deal with their
config themselves. RAID and LVM for example may need attention, but the
user is usually equipped to deal with that and knows what t do.
