After the launch of Citrix ADC VPX-customer licensed instance from the AWS marketplace, a license is required. For more information on VPX licensing, seeLicensing overview.

You have to:

  1. Use the licensing portal within the Citrix website to generate a valid license.
  2. Upload the license to the instance.

If this is apaidmarketplace instance, then you do not need to install a license. The correct feature set and performance activate automatically.

如果你使用Citrix ADC VPX实例模型number higher than VPX 5000, the network throughput might not be the same as specified by the instance’s license. However, other features, such as SSL throughput and SSL transactions per second, might improve.

5 Gbps network bandwidth is observed in thec4.8xlargeinstance type.

How to migrate the AWS subscription to BYOL

This section describes the procedure to migrate from AWS subscription to Bring your own license (BYOL), and conversely.

Do the following steps to migrate an AWS subscription to BYOL:

Note

TheStep 2andStep 3are done on the Citrix ADC VPX instance, and all other steps are done on the AWS portal.

  1. Create a BYOL EC2 instance usingCitrix ADC VPX - Customer Licensedin the same availability zone as the old EC2 instance that has the same security group, IAM role, and subnet. The new EC2 instance must have only one ENI interface.
  2. To back up the data on the old EC2 instance using the Citrix ADC GUI, follow these steps.
    1. Navigate toSystem > Backup and Restore.

    2. In theWelcomepage, clickBackup/Importto start the process.

    3. In theBackup/Importpage, fill in the following details:
      • Name- t的名字he backup file.
      • Level– Select the backup level asFull.
      • Comment– Provide a brief description of the backup.

    4. ClickBackup. Once the backup is complete, you can select the file and download it to your local machine.

  3. To restore the data on the new EC2 instance using the Citrix ADC GUI, follow these steps:

    1. Navigate toSystem > Backup and Restore.
    2. ClickBackup/Importto start the process.

    3. Select theImportoption and upload the backup file.

    4. Select the file.

    5. From theSelect Actiondrop-down menu, selectRestore.

      Restore file

    6. On theRestorepage, verify the file details, and clickRestore.

      Verify file for restore

    7. After the restore, reboot the EC2 instance.

  4. Move all interfaces (except the management interface to which the NSIP address is bound) from the old EC2 instance to the new EC2 instance. To move a network interface from one EC2 instance to another, follow these steps:

    1. In theAWS Portal, stop both the old and new EC2 instances.
    2. Navigate toNetwork Interfaces, and select the network interface attached to the old EC2 instance.

    3. Detach the EC2 instance by clickingActions > Detach.

      Detach EC2 instance in AWS

    4. Attach the network interface to the new EC2 instance by clickingActions > Attach. Enter the EC2 instance name to which the network interface must be attached.

      Attach network interface in AWS

    5. Do theStep 1toStep 4for all other interfaces that are attached. Make sure to follow the sequence and maintain the interface order. That is, first detach interface 2 and attach it, and then detach interface 3 and attach it, and so on.

  5. You can’t detach the management interface from an old EC2 instance. So, move all the secondary IP addresses (if any) on the management interface (primary network interface) of the old EC2 instance to the new EC2 instance. To move an IP address from one interface to another, follow these steps:

    1. In theAWS Portal, make sure that both the old and new EC2 instances are inStopstate.
    2. Navigate toNetwork Interfaces, and select the management network interface attached to the old EC2 instance.
    3. ClickActions > Manage IP Address, and make note of all the secondary IP addresses assigned (if any).
    4. Navigate to the management network interface or primary interface of the new EC2 instance.
    5. ClickActions > Manage IP Addresses.
    6. UnderIPv4 Addresses, clickAssign new IP address.
    7. Enter the IP addresses, which are noted in theStep 3.
    8. SelectAllow secondary private IP addresses to be reassignedcheck box.

    9. ClickSave.

      Move an IP address in AWS

  6. Start the new EC2 instance and verify the configuration. After all the configuration is moved, you can delete or keep the old EC2 instance as per your requirement.
  7. If any EIP address is attached to the NSIP address of the old EC2 instance, move the old instance NSIP address to the new instance NSIP address.
  8. If you want to revert to the old instance, then follow the same steps in the opposite way between the old and new instance.
  9. After you move from subscription instance to BYOL instance, a license is required. To install a license follow these steps:
    • Use the licensing portal in the Citrix website to generate a valid license.
    • Upload the license to the instance. For more information, seeVPX ADC - Install a new license.

Note

When you move BYOL instance to subscription instance (paid marketplace instance), you need not install the license. The correct feature set and performance is automatically activated.

Limitations

The management interface can’t be moved to the new EC2 instance. So Citrix recommends you manually configure the management interface. For more information, seeStep 5in the preceding procedure. A new EC2 instance is created with the exact replica of the old EC2 instance but only the NSIP address has a new IP address.
