/**
 * This test checks the upgrade path from noauth/nossl to x509/requireTLS.
 *
 * NOTE: This test uses ssl communication and therefore cannot test modes that
 * do not allow ssl. The first step in the full upgrade process is to restart
 * the each node into the "transitionToX509allowTLS" state and is tested in
 * the sslSpecial directory.
 *
 * This test requires users and data to persist across a restart.
