Upgrade a Citrix ADC VPX instance on AWS 编辑

You can upgrade the EC2 instance type, throughput, software edition, and the system software of a Citrix ADC VPX running on AWS. For certain types of upgrades, Citrix recommends using the High Availability Configuration method to minimize downtime.

Note:

• Citrix ADC software release 10.1.e-124.1308.e or later for a Citrix ADC VPX AMI (including both utility license and customer license) does not support the M1 and M2 instance families.
• Because of changes in VPX instance support, downgrading from 10.1.e-124 or a later release to 10.1.123.x or an earlier release is not supported.
• Most of the upgrades do not require the launch of a new AMI, and the upgrade can be done on the current Citrix ADC AMI instance. If you do want to upgrade to a new Citrix ADC AMI instance, use the high availability configuration method.

Change the EC2 instance type of a Citrix ADC VPX instance on AWS

If your Citrix ADC VPX instances are running release 10.1.e-124.1308.e or later, you can change the EC2 instance type from the AWS console as follows:

1. Stop the VPX instance.
2. Change the EC2 instance type from the AWS console.
3. Start the instance.

You can also use the above procedure to change the EC2 instance type for a release, earlier than 10.1.e-124.1308.e, unless you want to change the instance type to M3. In that case, you must first follow the standard Citrix ADC upgrade procedure, at, to upgrade the Citrix ADC software to 10.1.e-124 or a later release, and then follow the above steps.

Upgrade the throughput or software edition of a Citrix ADC VPX instance on AWS

To upgrade the software edition (for example, to upgrade from Standard to Premium edition) or throughput (for example, to upgrade from 200 Mbps to 1000mbps), the method depends on the instance’s license.

Using a customer license (Bring-Your-Own-License)

If you are using a customer license, you can purchase and download the new license from the Citrix website, and then install the license on the VPX instance. For more information about downloading and installing a license from the Citrix website, see the VPX Licensing Guide.

Using a utility license (Utility license with hourly fee)

AWS does not support direct upgrades for fee-based instances. To upgrade the software edition or throughput of a fee based Citrix ADC VPX instance, launch a new AMI with the desired license and capacity and migrate the older instance configuration to the new instance. This can be achieved by using a Citrix ADC high availability configuration as described in Upgrade to a new Citrix ADC AMI instance by using a Citrix ADC high availability configuration subsection in this page.

Upgrade the system software of a Citrix ADC VPX instance on AWS

If you need to upgrade a VPX instance running 10.1.e-124.1308.e or a later release, follow the standard Citrix ADC upgrade procedure at Upgrade and downgrade a Citrix ADC appliance.

If you need to upgrade a VPX instance running a release older than 10.1.e-124.1308.e to 10.1.e-124.1308.e or a later release, first upgrade the system software, and then change the instance type to M3 as follows:

1. Stop the VPX instance.
2. Change the EC2 instance type from the AWS console.
3. Start the instance.

Upgrade to a new Citrix ADC AMI instance by using a Citrix ADC high availability configuration

To use the high availability method of upgrading to a new Citrix ADC AMI instance, perform the following tasks:

• Create a new instance with the desired EC2 instance type, software edition, throughput, or software release from the AWS marketplace.
• Configure high availability between the old instance (to be upgraded) and the new instance. After high availability is configured between the old and the new instance, configuration from the old instance is synchronized to the new instance.
• Force an HA failover from the old instance to the new instance. As a result, the new instance becomes primary and starts receiving traffic.
• Stop, and reconfigure or remove the old instance from AWS.

Prerequisites and points to consider

• Ensure you understand how high availability works between two Citrix ADC VPX instances on AWS. For more information about high availability configuration between two Citrix ADC VPX instances on AWS, see Deploy a high availability pair on AWS.
• You must create the new instance in the same availability zone as the old instance, having the exact same security group and subnet.
• High availability setup requires access and secret keys associated with the user’s AWS Identity and Access Management (IAM) account for both instances. If the correct key information is not used when creating VPX instances, the HA setup fails. For more information about creating an IAM account for a VPX instance, see Prerequisites.
  • You must use the EC2 console to create the new instance. You cannot use the AWS 1-click launch, because it does not accept the access and secret keys as the input.
  • The new instance must have only one ENI interface.

To upgrade a Citrix ADC VPX Instance by using a high availability configuration, follow these steps:

1. Configure high availability between the old and the new instance. To configure high availability between two Citrix ADC VPX instances, at the command prompt of each instance, type:

   • add ha node <nodeID> <IPaddress of the node to be added>
   • save config

   Example:

   At the command prompt of the old instance, type:

   add ha node 30 192.0.2.30
   Done
