When you upgrade from an earlier version of BEMS, consider the following guidelines:

• Administrators must provide their Microsoft Active Directory user credentials to log in to the BEMS Dashboard during the upgrade.
• If you are upgrading multiple instances in a cluster, you must upgrade each computer that hosts an instance of BEMS.
• If multiple BEMS instances point to a shared (common) database, new features are not available until all instances are upgraded. Running in a mixed-version environment for an extended period is not recommended.
• Special characters, for example semicolon (;), at sign (@), and slash mark (/), are not supported for the BEMS service account.
