"man portmaster", near the bottom of the page, suggests making a list of all ports, updating the ports tree and fetching all new distfiles, and then deleting all ports before rebuilding when updating all ports as is advised after a major version upgrade.

But 'make delete-old-libs', done too soon, could possibly pull needed libraries out from under portmaster and pkg.

I'm thinking of upgrading from 9.2-STABLE to 11-current, jumping over 10.
