I wouldn't use something like Ghost, although such programs are available, to transfer to an SSD, it needs to be correctly formatted from scratch. If you have a typical Ubuntu single partition plus swap setup, you could use tar, from a live distro, to backup to a stick, but you have to jump through a few hoops if it is FAT formatted (because of the 4GB file size limit). USB to SATA adaptors are cheap (so cheap that some SSD kits come with them) and make the process so much simpler as you can have both drives connected at the same time.
