correct routine of updating installed ports?

[Choy Kho Yee]

Just want to confirm if this is the correct routine to update the 
installed ports.

  # cvsup -g -L 2 supfile
  # portsdb -uU
  # pkgdb -F
  # port_version
  # portupgrade -a

  And what does "make index" actually do? Do I need it?

  Thanks for any input.
