Countdown to LAS: Your Citrix Licensing Game Plan for the Next 6–7 Months

If you’re running Citrix on-prem, the clock is officially ticking. Citrix has announced the end of its legacy file-based licensing and the move to the License Activation Service (LAS). After April 15, 2026, products that still rely on file-based licenses will no longer function—LAS will be the only supported activation method for on-premises components. Citrix Cloud–only customers aren’t impacted by this change. 

Below is a practical field guide you can hand to your infra and licensing teams today.

What’s changing (in plain English)

  • File-based licenses reach EOL on April 15, 2026. No grace period after that date—systems using legacy licensing will lose functionality. 

  • LAS becomes mandatory for activating on-prem Citrix components (e.g., Citrix Virtual Apps and Desktops, NetScaler/ADC where supported). Staying supported means running LAS-compatible versions

  • Citrix Cloud–only environments aren’t affected by this transition. 

Why this matters

  • Operational risk: Licensing outages have historically caused avoidable downtime. LAS aims to remove license servers as single points of failure and automate entitlement updates. 

  • Supportability: Post-deadline, legacy licensing = out of support and potential service disruption. 

  • Security & modernization: Moving to current, supported versions tightens your exposure window and aligns with broader platform roadmaps. 

Who’s impacted

  • On-prem customers running Citrix products licensed via the traditional file-based model. You must move to LAS and be on LAS-compatible builds

  • Citrix Cloud–only customers: No action required for this specific change. 

Action plan: a pragmatic path to April 15, 2026

1) Inventory & assess (Week 1–2)

  • Identify every product using file-based licensing (CVAD, NetScaler/ADC, Provisioning, etc.).

  • Record current versions, license server details, and renewal dates.

  • Map each product to the required LAS-compatible version. (Start with Citrix’s “What’s New in Licensing” and product-specific LAS notes.) 

2) Version alignment (Weeks 3–8)

  • Build an upgrade matrix to get each product onto a LAS-ready release.

  • For CVAD and NetScaler, confirm exact build requirements and any interop considerations (Delivery Controllers, StoreFront, FAS, ADC firmware). 

3) Stand up LAS (Weeks 6–10)

  • Establish connectivity and register entitlements with LAS per Citrix guidance.

  • In staged/non-prod, activate a subset of components via LAS and validate usage reporting and entitlement updates. 

4) Cutover in waves (Weeks 10–16)

  • Migrate sites/farms/instances in controlled batches during maintenance windows.

  • Keep a rollback runbook (snapshots, config backups, license server fallback plan for the window before final retirement).

5) Harden & monitor (Ongoing)

  • Implement observability: alert on activation status, entitlement sync, and any session anomalies.

  • Document SOPs for renewals (LAS automates entitlement updates, but you still want governance checks). 

Technical checklist

  • CVAD: Confirm Delivery Controllers and licensing components are on LAS-compatible versions; plan the agent/VDAs upgrade path accordingly. 

  • NetScaler (ADC): Verify your firmware supports LAS and understand how your current license type maps under LAS (e.g., UHMC/CPL where applicable). 

  • Provisioning (PVS): Validate version requirements and complete any post-upgrade license configuration steps. 

  • Connectivity & egress: Ensure outbound rules and proxies allow required LAS endpoints (per product docs). 

  • Contracts & renewals: Coordinate with procurement so terms/quantities align to your LAS entitlements before cutover. (Citrix notes LAS will automate entitlement updates at renewal.) 

Risk scenarios to avoid

  • “We’ll do it next quarter.” After April 15, 2026, legacy file-based licenses stop working; delay risks outright service impact. 

  • Partial upgrades without LAS enablement. Being on a current build but not activated through LAS still leaves you exposed. 

  • Ignoring NetScaler. ADCs also move under LAS requirements; don’t let edge licensing be the bottleneck. 

FAQs (condensed)

  • Does this affect Citrix Cloud only deployments?

    • No—Citrix states Cloud-only customers are not impacted by the LAS transition. 

  • What happens if we don’t move by the deadline?

    • Citrix says legacy licensing will cease to function, leading to loss of functionality

  • Will we still need a license server?

    • LAS shifts activation and entitlement to a cloud service, reducing reliance on traditional license servers and associated outages. Review product docs for any component-specific services still required. 

Next steps you can schedule today

  1. Executive brief (30 mins): Confirm scope, budget owner, and deadline risk.

  2. LAS readiness workshop (2 hrs): Versions, upgrade matrix, maintenance calendar.

  3. Pilot cutover (1–2 weeks): One CVAD site + one ADC pair.

  4. Global rollout: Waves every 1–2 weeks with rollback checkpoints.
