Preparing the target disk with MBR or GPT or Dedicated (use GPT
except you have a good reason not to), then use dump + restore.
You can find more information here:

The advantage of dump | restore is that only blocks in use will
be copied, and it works on file system level (instead of disk
block level like dd). Initializing the target disk prior to
starting the copy operation will make sure the partition data
is being written to the correct places.
