License Activation Service

Last published : Sep 25, 2026
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 (Citrix Platform License/Universal Hybrid Multi-Cloud), legacy NetScaler Pooled licenses, and NetScaler Fixed term Bandwidth licenses. To remain supported, your {{page.citrix-adc-generic}} and {{page.adm-product-name-long}} 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, 13.1-37.246 (FIPS), 14.1-66.68 (FIPS)
  • NetScaler SVM: 14.1-51.x, 13.1-60.x
  • NetScaler Console Service: Supported from early September 2025.
  • NetScaler Console on-prem: 14.1-51.x
    Note: LAS support for Console on-prem is from release 14.1-51.x onwards. However, file-based licensing is deprecated as of April 15 2026 from Console on-prem releases 14.1-51.x onwards and 13.1-60.x onwards. If you upgrade to Console on-prem release 14.1-51.x or release 13.1-60.x or later, you can continue using file-based licensing until 15th April 2026. However you must upgrade to Console on-prem release 14.1-51.x or later, and switch to LAS before 15th April 2026 because Console on-prem 13.1 does not support LAS.
All the other forms of legacy {{page.citrix-adc-generic}} licenses such as {{page.citrix-adc-generic}} virtual CPU licensing (Pooled vCPU), {{page.citrix-adc-generic}} VPX Check-In and Check-Out (CICO), perpetual will not be supported with LAS. {{page.citrix-adc-generic}} 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.
Before starting your transition to LAS, we recommend reading LAS for NetScaler. This ensures that you understand the general prerequisites, the supported or unsupported license types, the accurate workflow for your specific license and deployment types along with other important information.
License Activation Service (LAS) is a cloud-based licensing solution that replaces traditional file-based licensing. LAS introduces new modules to activate Citrix and {{page.citrix-adc-generic}} products, providing a streamlined, modern approach to license management.
Notes:
  • LAS is a license mechanism, not a license type.
  • File-based licensing refers to the older method of licensing using manual entitlements. In this document, ‘File-based licensing’ and ‘manually managed entitlements’ are used interchangeably as they describe the same concept.
The following are the key benefits of LAS:
  • Automated entitlement delivery through an entitlement blob.
  • An external agent for licensing communication is optional.
  • LAS eliminates the need for Z-Cap software license files on the {{page.netscaler-mpx-long}}™ and SDX instances.
Note:
If you are new to {{page.adm-product-name-long}}, begin with Getting Started.
The following diagram is for LAS with Console service.

Prerequisites

To use LAS, ensure that you have completed the following prerequisites:
  • You must have a valid Citrix Cloud account. For more information about existing cloud accounts or to onboard new cloud accounts, see Account Management.
  • The Organization ID (Org ID) linked to the Citrix Cloud account used for the LAS activation workflow must possess valid purchased entitlements. To view the current entitlements, see Entitlements.
  • The {{page.citrix-adc-generic}} instance is running a LAS-compatible version.
  • The {{page.citrix-adc-generic}} instance is added as a managed instance in {{page.adm-product-name-long}}.

Automatic enablement and compatibility

LAS is automatically enabled on the {{page.adm-product-name-long}} service. Once enabled, all {{page.citrix-adc-generic}} Flexed and Pooled license entitlements appear in the {{page.adm-product-name-long}} GUI.
You can view your entitlements by navigating to NetScaler Licensing > License management > License Activation Service (LAS) tab.
License Activation Service
Notes:
  • The new Sync Licenses option allows you to manually trigger this synchronization on demand, ensuring entitlements are up to date immediately.
  • The default frequency for entitlement synchronization is once every 8 hours if LAS entitlements have not been synchronized with NetScaler Console service and once every 24 hours there after. For on-demand synchronization, click Sync Now.

NetScaler version compatibility for LAS

To use LAS, your {{page.citrix-adc-generic}} instances must be running one of the following minimum versions:
  • {{page.citrix-adc-generic}}: 14.1-51.x, 13.1-60.x, 13.1-37.246 (FIPS), 14.1-66.68 (FIPS)
  • {{page.citrix-adc-generic}} SVM: 14.1-51.x, 13.1-60.x
  • {{page.adm-product-name-long}} service: Supported from early September 2025.
  • {{page.adm-product-name-long}} on-prem: 14.1-51.x
Notes:
  • To use LAS, ensure that you have completed the following prerequisites:
    • The {{page.citrix-adc-generic}} instance is running a LAS-compatible version.
    • The {{page.citrix-adc-generic}} instance is added as a managed instance in {{page.adm-product-name-long}}.
  • For SDX appliances, upgrade the Management Service (SVM) to a LAS-supported build and transition to LAS-based licensing. The VPX build version does not impact LAS compatibility.
With file-based licensing, your applied entitlements and configurations are visible under NetScaler Licensing > License management> Manual License File management.
Manual License File management
Note:
LAS supports Flexed licensing (UHMC/CPL), Pooled bandwidth licensing, and Fixed-term bandwidth licensing. All other forms of legacy {{page.citrix-adc-generic}} licenses, such as Pooled vCPU and CICO, are not supported with LAS.

Transition to LAS

When you navigate to NetScaler Licensing > License management > License Activation Service (LAS), the {{page.citrix-adc-generic}} GUI dynamically updates based on the compatibility of your {{page.citrix-adc-generic}} instances.
A message appears in the GUI if you do not have any {{page.citrix-adc-generic}} instances that are on LAS-compatible versions. The message prompts you to upgrade or add a {{page.citrix-adc-generic}} instance.
Note:
If some of your {{page.citrix-adc-generic}} instances are upgraded to a compatible version, you can use LAS for those specific instances.
When one or more {{page.citrix-adc-generic}} instances are compatible with LAS, they are categorized into one of two groups:
  • License {{page.citrix-adc-generic}} instances with LAS
  • Migrate the licensed {{page.citrix-adc-generic}} instances to LAS
The GUI adjusts dynamically depending on whether you are a first-time LAS user (with zero instances migrated) or an existing user (who has already moved some instances to LAS and is now adding more).
Note:
Delete the local file-based licenses on the SVM once licensing or migration to LAS is complete. The file-based licenses are located in the SVM folder /mpsconfig/license and must be deleted from this folder using the shell prompt. This note applies to the License with LAS and Migrate to LAS workflows for both first-time and existing users.
