yes!  I like to make sure the new copy is good before I
remove the old.  I've had moves fail halfway and be a pain
to get back together.

I usually do something fairly cautious like this myself:

  cp -a /home/. /newplace/home/. \
  && mv /home /home.old \
  && ln -s /newplace/home/. /home

Then I check that everything still works ok before deleting 
the old dir.

Note that I don't typically map my physical partitions to
the traditional top level dirs.  I usually have a small / 
and large /big, and /home /usr /var are symlinks to /big/home 
/big/usr /big/var, etc.

Alternatively you could use LVM etc to resize volumes.  But
LVM seems complicated to me.
