Source upgrades suported over-release upgrade (currently 10-STABLE can be upgraded from 7.0, see Makefile.inc1). Source upgrade is self-contained and don't depend from environment. Contrary to binary upgrade may depend of environment: presents pkg.txz on ftp.freebsd.org, freebsd.org ovned by project and etc. As result, in case of bad design, you can't upgrade from 11.0 nowhere (ex: packages for 11.x outdated and deleted, pkg.txz from latest suported release can't be run on 11.0, pkg from 11.0 can't be parsed latest format). I am not averse to binary upgrade path like 11.0-12.last-14.last-15.last-16.last-18.0. I am disagree case when impossible to upgrade outdated install (because url is now incorrect, packages for outdated release removed or lost and etc).
