What Are Precautions for Version Upgrade?

If a new version of the CBH system is available, upgrade your CBH system to use the optimized or new system functions. For details, see Upgrading the Version of a CBH System.

Upgrading the CBH system version is free. Ensure that you are fully aware of the following impacts when you plan to upgrade the CBH system version:

• Before the upgrade

  Back up data to ensure 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, you are not advised to 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.

  

  To expand the capacity after CBH is upgraded, wait for 5 minutes and then perform the expansion.
