Whoa--hold on there!

portmaster -a
portupgrade -a

Both say "upgrade all installed ports that need upgrading".  Both can 
fail, but many people use them routinely.

portupgrade -af

means to force an upgrade of every installed port, even if it's already 
at the latest version.  Don't do this lightly!
