Before you begin
Make sure both the Managers meet the required system requirements as mentioned in Central Manager system requirements.
This section provides the steps to upgrade the primary and secondary Managers configured for Manager Disaster Recovery (MDR).
Note
If you are upgrading from the Manager version 9.2.7.31 or lower, or 9.2.9.8 or lower to the Manager version 9.2.9.12 or later, Trellix recommends you to suspend the MDR pair, upgrade the individual Managers and then resume the MDR pair.
Task
Using the Suspend MDR feature, suspend the MDR pair. Click Manager and select the root admin domain. Then go to Setup → MDR → Suspend MDR.
Upgrade the primary Manager to 10.1.
Upgrade the secondary Manager to 10.1.
Using the Resume MDR feature, make the primary the active Manager.
Make sure the latest 10.8.x signature set is present in both the Managers.
Differences in alerts displayed by the Managers
When you upgrade an MDR pair, the Manager currently being upgraded could miss the alerts during the upgrade window. However, its peer receives these alerts. After you successfully upgrade both the Managers, the missed alerts are updated for both the Managers during the next automatic synchronization. Note that the Managers synchronize every 10 minutes. Therefore, within 10 minutes after you upgraded the MDR pair, the alerts are synchronized.
