If a previous upgrade attempt has failed, you must resolve upgrade issues before attempting upgrade again. You can use the Central Administration Web site to find information about current and previous upgrade attempts and determine issues that may be preventing upgrade from succeeding. To do this in Central Administration, in the Upgrade and Migration section, click Check upgrade status.
