Verify the management type for the node. The upgrade process will be different for MDM managed and NFM-P managed nodes.

For operations performed on nodes discovered through mixed-mode or model-driven management, CLI access management must be enabled on the node. The following types of CLI access must be enabled, in the order shown: md-cli, and classic-cli.

For SR OS device commissioning information, see the Management Interface Protocol Configuration section in the adaptor documentation. For additional information if needed, see the NE documentation.

Start the upgrade operation; see How do I start or schedule a new operation?

View the operation in the Operations tab to monitor it; see How do I view current operations and executions?.

You can stop or pause an existing operation, and start or stop a phase within an operation. Operations can be paused manually by a user, or automatically by crossing a configured threshold (for example, percentage of failed executions). Phases that are waiting can be manually started, and a phase that is in progress can be stopped or paused.

• Pause: Executions already in progress continue to completion, and no more executions are started. The operation remains in the All Operations view, and can be unpaused using the Resume action.

• Stop: Executions already in progress continue to completion, and any executions that have not started are marked as failed.

See How do I start, stop, or pause an operation?.

When the upgrade is complete, the NE reboots and raises a reboot alarm. The reboot alarm triggers an NE-specific discovery scan. When the discovery scan detects a version change, the NE information is updated.

After the upgrade is complete, you can check the History list to verify success, troubleshoot failures, or check schedules for future operations. See How do I view the details of completed operations?

To perform a rollback, see How do I perform a rollback on a target in an operation?.
