Avi Vantage supports improved and more flexible methods for upgrading the Avi Vantage system. Starting with Avi Vantage release 20.1.1, Avi UI supports all the upgrade workflows using Avi UI too. This article explains the complete workflow for upgrading an Avi Vantage using various options. The followings are the additional features for the Flexible Upgrades using Avi UI:

The following sections explain the different options available for the Avi Vantage software’s upgrade process using Avi UI.
Uploading the Avi Vantage software is the first step in the Avi Vantage’s software upgrade process.

- Once the file is selected, the upload of the software image starts. The status of the image upload progress is available on the Avi UI, as shown below.
- After the image upload is complete, the software package is available under the Software tab.
Upgrading Avi Vantage System
Navigate to Administrator > Controller > System Update, select the image uploaded in the previous step and click on the UPGRADE option to start the upgrade process.
Select the Upgrade All Service Engine Groups check-box if selecting for the SE groups update along with the Avi Controller upgrade. Click on Continue to proceed with the Avi Controller and SE groups software upgrades.

- When selecting the SE group update, the following two options are available to choose when the SE groups updates fail:
- Continue – The upgrade process for SE groups continues in the event of an error, failure, or any issues.
- Suspend – The upgrade process will not progress in the event on an error, failure, or any issues.
- Confirm that backup of configuration has been performed.
The progress for the update process is available on the Avi UI under the In Progress, section as shown below. The Controller Updating to 20.1.1 is available to confirm the update progress tracking.
Once the upgrade process is complete, the latest software version will be under the Administrator > Controller > System Update tab. There will be the current tag next to the updated software version, as shown below.
Once the Avi Controller upgrade is successful, the Service Engine group upgrade is initiated as the SE group upgrade was chosen in step no. 2. The following screenshot exhibits the message regarding the SE group update status.
