Well worth doing. That approach has saved my neck a few times when things have 
gone pear shaped with dependency issues after pkg upgrade has reinstalled a few 
hundred packages.

I normally create a new BE and chroot into it to do the upgrade. That way the running 
system isn't interrupted even if the upgrade goes disastrously wrong. If the upgrade 
looks OK it's then just a case of rebooting with the new BE at a convenient time.
