Can you elaborate pls.?
My current "home" is in "/"; so why move it there, it is already there.  
I don't have extra disk around, but I could copy /home over network to another PC.

I was planning to move "home" to another partition as I plan to wipe old installation (it is impossible for me to upgrade); it will be easier to reinstall.
My old installation is: 
Portage 2.3.24 (python 3.5.4-final-0, default/linux/amd64/17.0/desktop, gcc-6.4.0, glibc-2.25-r10, 4.9.72-gentoo x86_64)

Since, old installation has home or "/" (root) partition, if I wipe the root, home will be gone as well.  So I was planning on moving "home" to another partition, this way all data will be there.
So, after moving "home" to another partition "sda5" I can wipe the "sda4" and re-install gentoo.  "home" data would not be touched by upgrade.
