Upgrading NetScaler MAS to the 12.1 Release

Download the upgrade package from the NetScaler MAS Downloads page and follow the instructions in this section to upgrade your system to the latest 12.1 build. After the upgrade process has begun, NetScaler MAS restarts. All existing connections are then terminated and reconnected when the upgrade is completed successfully. The existing configuration is preserved, however NetScaler MAS does not process any data until the upgrade is successfully completed.

Points to note before upgrading to 12.1

  • With 12.1, the high availability deployment can configure a floating IP address on the primary node and eliminate the need for a separate NetScaler load balancer. Because of this improvement, the high availability deployment must be on the same subnet. If your current deployment is on different subnets, you must review the Upgrade document to learn about the upgrade process.

  • With 12.1, the advanced backup support has been removed. The advanced backup feature is no longer available after you upgrade to NetScaler MAS 12.1. Review the Upgrade document for more details.

  • Back up the NetScaler MAS server before you upgrade.

  • After the upgrade, you might have to reestablish connections between the NetScaler MAS server and the managed instances. A confirmation prompt warns you that connections can fail if you proceed.

  • For NetScaler MAS servers in high availability setup, when upgrading, do not make any configuration changes on either of the nodes.

  • It is also important to understand the licensing framework and types of licenses before you start to upgrade. For NetScaler MAS licensing information, see Licensing.

For more information, see Upgrade.
