/* Purpose of this test is to verify simplest part of upgrade logic.
 * Start by creating two very simple 4.x environments,
 * one in each of two states:
 *  - after a clean shutdown
 *  - without a clean shutdown
 *
 * The two different environments will be used to exercise upgrade logic
 * for 5.x.
