Licensing overview

Last published : Sep 24, 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 (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, 13.1-37.246 (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 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.
NetScaler offers a wide range of product editions and licensing models for MPX and VPX appliances, to meet your organization's needs.
For proper operation of a NetScaler appliance, it must have one of the NetScaler family edition licenses. The ADC product line has three family editions:
  • Standard Edition
    Note
    The standard edition has reached End-of-Sale (EOS) and is only available for renewal.
  • Advanced Edition
  • Premium Edition
For more information, see the data sheet. The data sheet is available on www.netscaler.com.
Select a NetScaler edition. Then select an MPX or a VPX license offering based on the following criteria:
  • Perpetual and subscription (yearly and hourly subscription)
  • vCPU and bandwidth
  • on-premises and cloud
Important:
Starting from NetScaler release 14.1-51.x, there are some changes related to perpetual licensing. For details, see Changes related to perpetual licensing.

NetScaler VPX Express license

VPX Express for on-premises and cloud deployments does not require a license file, and it offers the following features:
  • 20 Mbps bandwidth
  • Starting with NetScaler release 14.1 build 29.65, VPX Express includes all the advanced features that are available with the Premium license.
  • Maximum 250 SSL sessions
  • 20 Mbps SSL throughput

NetScaler fixed bandwidth (throughput) license

Fixed bandwidth perpetual licenses are EOS and you must now use fixed bandwidth subscription licenses. Fixed bandwidth subscription allows you to run a fixed throughput deployment in any form factor (MPX/SDX/VPX/BLX). After deploying your NetScaler, you must fetch your license files from the license server and download a license manually to each device (on-premises or cloud) or use LAS-based licensing. For more information on LAS, see License Activation Service.
Notes:
  • NetScaler instance stops its normal operations after the license expiry, including configuration loss and complete shutdown of traffic processing.
  • Only advanced and premium editions are supported.
  • Edition and bandwidth upgrades are not supported.
  • Migration to pooled capacity license is not supported.

NetScaler Flexed license

NetScaler Flexed licensing is the new licensing framework aimed at simplifying the license management process. Your Flexed license includes software instance licenses (VPX/CPX/BLX, SDX, and MPX) and bandwidth capacity licenses. You must apply the Flexed licenses on the NetScaler Console service or NetScaler Console on-prem. You can then allocate them across all NetScaler form factors deployed in cloud or on-prem.
For more information about Flexed licenses on NetScaler Console, see Flexed license.
For more information about Flexed licenses on NetScaler Console service, see Flexed license.

NetScaler Pooled license

Use NetScaler Console to create a licensing framework that comprises a common bandwidth and an instance pool. For more information, see NetScaler Pooled Capacity.
Note:
NetScaler Console can host both Pooled and Self Managed Pool licenses. To use the required license, configure the license server on NetScaler and check out the capacity from the appropriate pool. The ADC CLI and GUI configuration steps for the Pooled and Self Managed Pool license are the same.

NetScaler Self Managed Pool license

From NetScaler release 13.1 build 30.x onwards, NetScaler instances support the Self Managed Pool license. With this license, you can simplify and automate license file uploads to a license server. Use NetScaler Console to create a licensing framework that comprises a common bandwidth or vCPU and instance pool.
To use the Self Managed Pool license, configure the license server to the SelfManagedPool license mode on NetScaler and check out the required capacity. Use the show ns license command after rebooting the NetScaler appliance to find out the license that is configured.
Important
If your system is configured with Pooled Capacity license but want to migrate to Self Managed Pool license without impacting the traffic flow, ensure that the target server has the required Self Managed Pool license.
You can migrate only between the following compatible licenses:
  • Pooled Capacity to Self Managed Pool, and conversely.
  • vCPU to Self Managed vCPU, and conversely.
To migrate the license, run the following command:
add ns licenseserver (<licenseServerIP> | <serverName>) -forceUpdateIP -licensemode [CICO | Pooled | SelfManagedPool | VCPU | SelfManagedvCPU]
Example:
add licenseserver 192.0.2.246 -forceUpdateIP -licensemode selfManagedvcPU

Configure Self Managed Pool license using the CLI

To add the license server config to the NetScaler appliance, run the following command:
add ns licenseserver (<licenseServerIP> | <serverName>) [-port <positive_integer>] -licensemode [CICO | Pooled | SelfManagedPool | VCPU | SelfManagedvCPU]
Example:
add ns licenseserver 192.0.2.246 -port 27000 -licensemode SelfManagedPool
Note:
The show ns licenseserverpool command displays only licenses based on the specified license mode. Hence, the licenses are fetched faster. To get an inventory of all the licenses, run the show ns licenseserverpool -getallLicenses command. If the license mode is not specified, the Pooled Capacity licenses are displayed by default.
To modify the system capacity, run the following command:
set ns capacity ((-bandwidth <positive_integer> -unit ( Gbps | Mbps )) | -platform <platform>) [-Edition <Edition>]
Example:
set ns capacity -bandwidth 3 -unit gbps -edition enterprise
Note:
Capacity is checked out from the license pool of the license server.
To reboot the NetScaler appliance, run the following command:
reboot [-warm]
To display the state of all the licensed features and configured license mode, run the following command:
show ns license
Sample output of show ns licenseserverpool command:
show ns licenseserverpool command output
Sample output of show ns licenseserverpool -getallLicenses command:
show ns licenseserverpool -getallLicenses command output
Sample output of show license command:
show license command output

Configure Self Managed Pool license using the GUI

Complete the following steps to configure the Self Managed Pool license:
  1. Navigate to System > Licenses > ADC License > Manage Licenses > Add New License.
  2. In the Licenses page, select the Use remote licensing radio button, and choose your license mode from Remote Licensing Mode.
  3. Enter the server IP address and the license port details.
  4. Provide the NetScaler Console access credentials.
  5. Click Continue.

Changes related to perpetual licensing

Terminology description:
  • Subscription Advantage (SA) Date: A date present in perpetual license files, introduced to limit upgrades to NetScaler versions released only up to a certain date.
  • Burn-In Date (BID): A date associated with every NetScaler version and build.
The following changes are introduced in Perpetual licensing:
Change 1: SA Date check and enforcement:
This check and enforcement is introduced to block NetScaler customers who are running NetScaler instances on perpetual licenses with expired maintenance, resulting in unsupported deployments.
If the Burn-In Date of the NetScaler build to which you are trying to upgrade to is later than the SA date in the perpetual license file used on your NetScaler instance, your NetScaler instance becomes unlicensed after the upgrade. Some NetScaler VPX™ versions already had this check and enforcement. It is now introduced for NetScaler form-factors: VPX, MPX, and SDX starting from the following NetScaler releases:
  • NetScaler ADC: 14.1 51.x, 13.1-60.x, 13.1-37.x (FIPS)
  • NetScaler SVM: 14.1 51.x, 13.1-60.x
To find the SA date of the perpetual license used on your NetScaler instance, see your perpetual license file for the SA date in YYYY.MMDD format as shown in the following sample image.
SA Date
This check occurs during boot up after a NetScaler upgrade. To avoid your NetScaler instance becoming unlicensed, obtain a supported NetScaler license with active maintenance.
Note:
If you are using a perpetual license on your NetScaler instance and have active maintenance, but have not replaced the old perpetual license file with the license file provided with your latest maintenance renewal (that is, you did not use the latest license file with updated SA date and are still using the older license file with old SA date), your NetScaler becomes unlicensed if you upgrade to NetScaler builds that have the SA date check and enforcement. To avoid this impact, use the latest file that you received during your most recent maintenance renewal.
Change 2: Burn-In Date specific to each build:
Earlier, the Burn-In Date for all builds across a major NetScaler version used to be the same. For example, all builds under NetScaler version 14.1 used to have the same Burn-In Date. Now, each unique NetScaler build has its own Burn-In Date (approximately based on its release date) starting from the following NetScaler releases:
  • NetScaler ADC: 14.1-51.x, 13.1 60.x, 13.1 37.x (FIPS)
  • NetScaler SVM: 14.1-51.x, 13.1 60.x
For example, from NetScaler version 14.1 build 51.x onwards, each build has a different Burn-In Date.
The following table lists the Burn-In Dates for various NetScaler releases and builds:
NetScaler Version Build Number Burn-in Date
14.1 All builds older than 51.72 Jul 12, 2023
14.1 51.72 Sep 2, 2025
14.1 56.74 Nov 9, 2025
14.1 60.52 Dec 3, 2025
13.1 All builds older than 60.32 Aug 23, 2021
13.1 60.32 Oct 31, 2025
13.1 61.25 Nov 27,2025
13.1 (FIPS) All builds older than 37.250 Aug 23, 2021
13.1 (FIPS) 37.250 Oct 31, 2025
13.1 (FIPS) 37.255 Dec 2, 2025
