Changing profile to multilib

I've been Googling around but I can't seem to find the steps for changing profile on Gentoo. I want to switch from hardened/linux/amd64/no-multilib to hardened/linux/amd64 as I want multilib. I've been unable to install memtest86+, and I really need to test the memory. If someone could advise me of the steps to switch profile, it would be appreciated.

I know how to change it with eselect, I'm unsure how to emerge it. I think an "emerge --update --deep --with-bdeps=y @world" would work, but I don't want to break the system.

Hello,

You need a multilib version of glibc, from a tinderbox or a multilib stage3. It must be the same version as yours, and with the same CFLAGS.
Build a binpkg from it, then deploy it to your no-multilib environment, then emerge -1 binutils gcc glibc, then emerge -DuNav @world.

But the simplest solution is to reinstall.

Or you could just download system rescue cd and use the memtest from there.
