<?php // This migration once upgraded VCS password hashing, but the table was // later removed in 2018 (see T13043). // Since almost four years have passed since this migration, the cost of // losing this data is very small (users just need to reset their passwords), // and a version of this migration against the modern schema isn't easy to // implement or test, just skip the migration. // This means that installs which upgrade from a version of Phabricator // released prior to Feb 2014 to a version of Phabricator relased after // Jan 2018 will need to have users reset VCS passwords.
