When upgrading secondary Administration servers, you can upgrade each server as needed, depending on your administration requirements. Also consider how you plan to upgrade and deploy the DRA user interfaces. For more information, see Deploying the DRA User Interfaces.
For example, a typical upgrade path may include the following steps:
Upgrade one secondary Administration server.
Instruct the AAs who use this server to install the appropriate user interfaces, such as the Account and Resource Management console.
Repeat Steps and Step 2 until you completely upgrade the MMS.
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. When you complete the upgrade process for this MMS, and all AA client computers are running upgraded user interfaces, take any remaining previous DRA version servers offline.
