If you must copy exactly what you currently have then I'd use a
variation on the handbook method which has already been suggested at

Rather than example 18-1 or 18-2 I'd pipe dump directly into restore. Do
this once for every filesystem. Something like:

( cd /; /sbin/dump -0uanf - / ) | ( cd /newmount; /sbin/restore -rf - )

Where /newmount is the temporary new mount point for your new drive.
Left preparation of new disk as an exercise for the reader.

However there is a good argument to be made for making a totally new
installation of FreeBSD. Then go through the original disk picking up
the necessary files to customize for your use. As you find these files
put their names in a file named something like files.list that in the
future one could "tar -T files.list" (thats an incomplete example) to do
a minimal quick backup or restore of only the files which are unique to
your machine. This is an opportunity to find these files, and to
practice using tar -T to lift them from one drive and write them to

I wouldn't try to move the ports collection with the above technique.
However it would be a good idea to save a list of installed ports that
one could use to reinstall.
