Upgrading the vSRX

There are several methods and considerations that you must understand before you upgrade your IBM Cloud® Juniper vSRX:

vSRX version level
Bare-metal server processor model
Bandwidth: 1G versus 10G
Stand-alone or High Availability (HA)

Using these factors, the following table lists whether you can use the OS reload option to upgrade your vSRX. The table also describes whether rollback is supported for the upgrade. Other considerations include whether you need a manual vSRX configuration migration to complete the upgrade.

Reference the following table to determine whether you can upgrade your vSRX by using OS reload. For more information, see General upgrade considerations.

For more information, see IBM Cloud Juniper vSRX supported versions.

The upgrade reapplies the license that is currently applied to the nodes. It does not update the license. To update to a newer license, you must separately run the license renewal steps. For more information, see Renewing a vSRX license.
