Upgrade A10 Control

Upgrading A10 Control ensures access to the latest features, enhancements, and fixes.

Before starting the upgrade, review all prerequisites and confirm cluster health, backups, and license requirements. For any assistance with the upgrade steps, contact the A10 Networks Support.

Supported Upgrade Path

The following upgrade paths are supported:

Current Version	Target Version
A10 Control 1.4.0 A10 Control 1.5.0	A10 Control 1.5.1

NOTE:

A10 Control does not support changing between IPv4 and IPv6 during an upgrade.

Key Considerations

• Management and device licenses are preserved across upgrades, and reapplication of entitlements is not required unless the licensing model changes.

• Only the super-admin user can perform the upgrade.
• In a multi-node deployment, the upgrade must always be initiated from the master node. Once triggered, the upgrade automatically propagates to all other nodes in the cluster.

NOTE:

Security feature is added for changing the default super-admin SSH password upon first login. You must SSH as super-admin user in all 3 nodes at least once and change the default password before upgrading the Multi-node setup from 1.4 to higher version.

Upgrade Workflow

To upgrade an A10 Control instance, perform the following:

1. Verify prerequisites.

   • Confirm registered ACOS Thunder devices are compatible with the target A10 Control version. For more information, see A10 Control Compatibility Matrix .
   • Take a complete backup. For more information, see Backup and Restore .

   • Ensure sufficient disk space on the A10 Control master node.

     The requirement is: 150 GB + 5% of the root partition size.

     To verify available disk space, run the following command:

     $ df -h /

     Example

     If the root partition size is 628 GB.

     Minimum required free space = 150 GB + (5% of 628 GB) = 181 GB.

     Filesystem                     Size  Used  Avail  Use%  Mounted on
     /dev/mapper/vg_main-lv_root    628G  381G  216G   64%   /
     

     Since 216 GB is available, the upgrade can proceed.

     If the available space is below this threshold, free up space or add storage before proceeding.

2. Download the upgrade package. For more information, see Download the Upgrade File.

3. Upgrade and verify.

   1. Run the upgrade command on the master node.

   2. Monitor the upgrade progress.

   3. Reboot all the nodes from GUI.

   4. After completion, verify that the upgrade was successful.
