Upgrading the CBH System Version

A CBH system of the latest version has system optimizations or new functions. To use those functions, upgrade your instances in a timely manner.

Precautions

  • Before the upgrade
    • Back up data to ensure a quick rollback in case of upgrade failures.
  • During the upgrade

    The version upgrade takes about 30 minutes. Although the CBH system is unavailable during this period, there is no impacts on host resources managed on the instance. However, to prevent important data loss, do not log in to the CBH system during the version upgrade.

  • After the upgrade

    The CBH instance automatically restarts after the upgrade completes. You can then use the mapped CBH system.

    After the upgrade, you can use the configuration and storage data of the original CBH system. Version upgrading does not affect the original configuration and storage data of the CBH system.

  • Rolling Back the Upgrade

    After the version upgrade is complete or during the cross-version upgrade, you can roll back the upgrade on the bastion host details page. After the rollback starts, the status of the bastion host changes to Rolling back edition.

    After the rollback, the basion host will restore to what it is before the upgrade. Data changes and new data will be lost as the basion host will be interrupted during the rollback. Exercise caution when performing this operation.

Constraints

  • In the new version of CBH, the application publish function is optimized. After the upgrade, to use the application O&M functions as usual, install the required plug-in on the application publish server as prompted.
  • To upgrade version 3.3.40.0 and 3.3.41.0, synchronize the time of OBS buckets first.

Prerequisites

  • The CBH system data has been backed up.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner of the management console and select a region or project.
  3. In the navigation pane on the left, click and choose Security & Compliance > Cloud Bastion Host to go to the CBH console.
  4. Locate the row containing the instance you want to upgrade. In the Operation column, choose More > Upgrade > Upgrade Edition.
  5. In the displayed dialog box, select the schedule upgrade time and enter UPGRADE to confirm. To cancel the upgrade schedule, enter CANCEL in the dialog box. You can also change the upgrade schedule you set before.

    Upgrade types:

    • During a minor version upgrade, the CBH instance you are using will be interrupted. It takes about 15 to 30 minutes to complete the upgrade.
    • During the cross-version upgrade, a new CBH instance will be created, and the CBH instance you are using will be interrupted. It takes about 30 minutes to 2 hours to complete the upgrade. During the cross-version upgrade, the instance status changes to Upgrading first, and then to Migrating data, Configuring HA, and to Running.

  6. Wait for the upgrade to complete. It takes about 15 minutes to 2 hours for the upgrade to finish at the backend. The actual upgrade time varies depending on the upgrade type. Once the upgrade starts, the instance status changes to Upgrading.
  7. When the CBH instance status changes to Running, the CBH system is available.

    After the upgrade completes, you can verify the upgrade. To do so, click the instance name in the Instance Name column. On the displayed page, check the instance version. If the instance version has not changed, the upgrade fails. In this case, contact technical support.
