After you successfully prepare your MMS, upgrade the primary Administration server. Do not upgrade user interfaces on the AA client computers until you complete upgrading the primary Administration server. For more information, see Deploying the DRA User Interfaces.
NOTE:For more detailed upgrade considerations and instructions, see the Directory and Resource Administrator Release Notes.
Before you upgrade, notify your AAs when you plan to start this process. If you dedicated a secondary Administration server to run a previous DRA version, also identify this server so AAs can continue using the previous DRA version during the upgrade.
NOTE:Once you upgrade the primary Administration server, you cannot synchronize delegation, configuration, or policy settings from this server to secondary Administration servers running a previous DRA version. Also, your AAs cannot connect to the primary server until you upgrade the user interfaces on their client computers.
