I would recommend:
- install SSD
- partition SSD, aligning partitions with new block sizes
- create filesystems in SSD partitions
- copy over filesystems with rsync
- make changes to new /etc/fstab
- make changes to bootloader to set new root filesystem
- shut down machine
- disconnect old disks
- start machine, make BIOS changes if necessary
- boot
- test for functionality
file-level copying is better than block-level copying when going
between drives of different technologies.
