Yes. And good chance you'll need to run dracut to rebuild all initramfs's; for sure if it's being moved to new hardware. It might tolerate same hardware, different drive and fs volume UUID, but I know that the initramfs contains references to the volume UUID so you're better off rebuilding the initramfs's.
