Assuming that you can connect both, create the partitions on the SSD, put a
filesystem on each SSD partition, and mount everything.
mount /dev/sda2 /old_disk # root
mount /dev/sda1 /old_disk/boot # boot
mount /dev/sdb2 /new_disk
mount /dev/sdb1 /new_disk/boot
cp -a ./ new_disk/
The archive options of cp (as root) should copy everything.
Instead of the cp you could use rsync:
rsync -a /old_disk/ /new_disk/ # type as shown, trailing / needed
Then chroot to the new disk root and install grub.
