Yes, the chroot part is very brief on the guide I linked to.  I did that
part nearly the same way as Hika did.  I also did (after the chroot)

grub2-mkconfig -o /boot/grub2/grub.cfg

It will update the grub config with the new UUIDs from the new partitions
on the SSD disk you have installed.  I am not sure if that is necessary,
but it doesn't hurt, either.

I am running Fedora.  I believe the command is slightly different in other
flavors of Linux.

Upgrading disks is a regular thing.  When you decide on a solution,
document it / take notes for yourself so the next time is easier.
