Transition to Flexed licensing

September 12, 2025
Contributed by:

Important:

File-based licensing system (also referred to as manually managed entitlements), traditionally used for activating various on-premises components, will be End of Life (EOL) on April 15, 2026. License Activation Service (LAS) is the next generation technology for product activations across the suite of Citrix products. LAS will be the only way to activate and license NetScaler instances after April 15, 2026, supporting NetScaler Flexed licenses (CPL/UHMC), legacy NetScaler Pooled licenses, and NetScaler Fixed term Bandwidth licenses. To remain supported, your NetScaler and NetScaler Console deployments must be on a LAS compatible version.

The minimum required NetScaler versions that are LAS compatible are:

  • NetScaler ADCs: 14.1-51.x, 13.1-60.x, 13.1-37.x (FIPS)

  • NetScaler SVM: 14.1-51.x, 13.1-60.x

  • NetScaler Console Service: Supported from early September.

All the other forms of legacy NetScaler licenses such as Pooled vCPU, CICO, perpetual will not be supported with LAS. NetScaler instances leveraging perpetual licenses without an active maintenance will become unlicensed upon upgrade to the above mentioned software versions.

LAS-based licenses may not be available to customers where prohibited by law or regulations.

If you have questions or concerns, contact Customer Care. Citrix may limit or suspend your Citrix Maintenance for non-compliance with these requirements without liability in addition to any other remedies Citrix may have at law or equity. These requirements don’t apply where prohibited by law or regulation.

Read the following note before proceeding further.

Note:

You must switch to the Flexed licensing before the expiry of your current license. While planning the transition keep the following steps in mind, and plan a maintenance window if the steps involve a license reconfiguration or NetScaler reboot.

Pooled bandwidth license to Flexed license

Some steps are common to MPX, SDX, and VPX. These steps are listed first, followed by the steps specific to MPX, SDX, or VPX.

Common steps for VPX/MPX/SDX

  1. Upload and apply Flexed software licenses on NetScaler Console. See License files.
  2. If you have a Z-Cap software license for a specific period, apply that license on NetScaler hardware (MPX/SDX).

For VPX/MPX

The following additional steps are needed:

  1. If you have a Pooled Premium (Platinum) bandwidth license, the license automatically switches to Flexed after the expiry of the old license.
  2. If you have a Pooled Standard or Pooled Advanced bandwidth license, manually check out Premium bandwidth and warm reboot NetScaler.

For SDX

Note:

Ensure that you switch to the Flexed license before the expiry of your current license.

The following additional steps are needed:

  1. Check out the required instance and bandwidth license from Flexed license to SDX. SDX reboot is not required.
  2. If all VPX on SDX have a Premium edition, the license automatically switches to Flexed after the expiry of the old license.
  3. Change the edition for all the VPX (on SDX) with Standard or Advanced to Premium. These VPX instances are automatically rebooted.
  4. Reduce the Standard and Advanced bandwidth capacity on SDX to zero.

Pooled vCPU to Flexed bandwidth capacity

For VPX

  1. Upload and apply Flexed software Licenses on NetScaler Console. See License files.
  2. Remove the existing license server using the NetScaler GUI. NetScaler is unlicensed until all the steps are completed.
  3. Add the license server with Flexed/Pooled option.
  4. Check out the required instance and bandwidth licenses to NetScaler.
  5. Warm reboot NetScaler.

For CPX

  1. Upload and apply flexed licenses on NetScaler Console. See License files.

  2. Update the CPX YAML or HELM manifest file with bandwidth requirements. See CPX bandwidth-based licensing.

  3. Deploy CPX instance using kubectl apply -f cpx.yaml command or using the HELM chart.

Fixed subscription or Perpetual license to Flexed license

Some steps are common to MPX, SDX, and VPX. These steps are listed first, followed by the steps specific to MPX, SDX, or VPX.

Common steps for VPX/MPX/SDX

  1. Onboard to NetScaler Console.
  2. Upload and apply Flexed software licenses on NetScaler Console. See License files.
  3. Apply Z-Cap software license on NetScaler hardware (MPX/SDX).

For VPX/MPX

The following additional steps are needed:

  1. Check out the required instance and bandwidth licenses to NetScaler.
  2. Warm reboot NetScaler.
  3. Delete the Fixed subscription license after NetScaler reboots.

For SDX

The following additional steps are needed:

  1. Check out the required instance and bandwidth license from Flexed license on SDX.
  2. If all VPX on SDX have the premium edition, SDX reboot is not required.
  3. If any VPX has the advanced or standard edition, that VPX must be shifted to the premium edition. The VPX automatically reboots.
  4. Apply Z-Cap software license on NetScaler SDX.
  5. Check out the required instance and bandwidth license from Flexed licensing on SDX.
  6. Delete the Fixed subscription license after NetScaler reboots.

CICO to Flexed bandwidth capacity

For VPX

  1. Upload and apply Flexed software Licenses on NetScaler Console. See License files.
  2. Remove the existing license server using the NetScaler GUI. NetScaler is unlicensed until all the steps are completed.
  3. Add the license server with Flexed/Pooled option.
  4. Check out the required instance and bandwidth licenses to NetScaler.
  5. Warm reboot NetScaler.
