The pave tests check that an upgrade build can be paved using Zedboot from the downgrade build. This can be done by running:
% $(fx get-build-dir)/host_x64/e2e_tests_pave \ --ssh-private-key ~/.ssh/fuchsia_ed25519 \ --downgrade-builder-name fuchsia/global.ci/core.x64-release-nuc_in_basic_envs \ --upgrade-builder-name --upgrade-fuchsia-build-dir $(fx get-build-dir) \ -device-hostname <IP-ADDRESS>
