Cluster Upgrade from ACOS 4.x or ACOS 5.x to ACOS 6.x

A10 Control can manage devices running ACOS version 6.x and later. Devices currently running older versions, such as 4.x or 5.x, must be upgraded to 6.x before they can be managed by A10 Control. For a seamless upgrade, A10 Control includes a utility that allows these devices to be upgraded to version 6.x.

This feature is disabled by default and must be enabled under Controller > Settings > System > Platform > Legacy Device Upgrade before starting the upgrade process.

NOTE:

The cluster upgrade supports single cluster, VRRP-A, High Availability (HA), VCS pair, and TPS device clusters. The older device upgrade is supported from ACOS 6.0.5 version onwards. Before proceeding with the upgrade process, verify whether the upgrading prerequisites are met. For the prerequisites information, see Upgrading to ACOS 6.0.5.
