Every IT administrator managing virtualized environments faces a familiar challenge: “How long will my current Citrix version be supported?” This concern becomes even more critical in enterprise environments where business continuity is paramount. Today, we’ll provide a comprehensive overview of Citrix Virtual Apps and Desktops end-of-life schedules across all versions, along with practical information to help you prepare for the future.

1. Understanding Citrix Virtual Apps and Desktops

Citrix Virtual Apps and Desktops (CVAD) is a virtualization solution that enables application and desktop delivery to any device, anywhere, while maintaining IT control over virtual machines, applications, and security. Previously known as XenApp and XenDesktop before the 2018 rebrand, this solution is now the cornerstone of hybrid work and digital workspace strategies for organizations worldwide.

CVAD centralizes the management of virtualized applications and desktops while delivering a local-like experience to end users. For IT departments, it enhances security and management efficiency, while users gain access to their work tools from anywhere, at any time.

2. Understanding CVAD Release Models – Two Tracks with Support Phases

CVAD offers two release tracks, each with its own tiered support structure. Understanding this is essential for effective version management.

Support Phase Definitions:

• Active Support: Full support including new features, security patches, and bug fixes
• Security Support: Limited to security patches and critical bug fixes (no new features)
• Extended Support: Paid option providing additional support after Security Support ends

Current Release (CR)

• Quarterly releases focused on delivering the latest features
• Active Support ends 6 months after release
• Security Support ends 18 months after release (complete EOL)
• Ideal for environments that want rapid access to new capabilities
• No Extended Support option available

Long-Term Service Release (LTSR)

• Released every 2-3 years for long-term stability
• Both Active Support and Security Support end 5 years after release
• Optimized for enterprise environments prioritizing stability
• Extended Support option available for additional 5 years (total 10-year lifecycle)

3. Detailed LTSR Version Support Schedule

Here’s the complete support timeline for LTSR versions most commonly used in enterprise environments, broken down by support phases.

Key Points:

• 7.15 LTSR: Active/Security Support ended, only Extended Support available (paid)
• 1912 LTSR: Completely end-of-life as of December 2024, immediate upgrade required
• 2203 LTSR: Currently in Active Support with approximately 2.5 years remaining
• 2402 LTSR: Latest LTSR offering full support for the next 5 years

Extended Support Options: LTSR versions can receive paid Extended Support after Security Support ends. This is typically purchased in 6-month increments and requires pre-approval from Citrix.

4. Complete Current Release Version Support Schedule

Current Releases have an 18-month support lifecycle, transitioning from Active Support to Security Support after 6 months. Below is the detailed support schedule for all CVAD Current Release versions.

4-1. Currently Supported Current Release Versions

4-2. End-of-Life Current Release Versions

Current Release Management Key Points:

• Active Support Period (first 6 months): Full support including new features, security patches, and bug fixes
• Security Support Period (next 12 months): Security patches and critical bug fixes only (no new features)
• Regular Upgrades Essential: CR users should plan upgrades at least every 6 months
• Test Environment Required: Adequate validation time before production deployment

5. Critical Notice – Licensing System Changes

There’s an important change that all CVAD administrators must be aware of:

File-based Licensing System EOL

• End Date: April 15, 2026
• Replacement Technology: License Activation Service (LAS)
• Required Action: Upgrade to LAS-compatible version before April 2026

LAS-Compatible Minimum Version Requirements:

• CVAD 1912 LTSR CU7 or later
• CVAD 2203 LTSR CU3 or later
• CVAD 2402 LTSR (all versions)

Missing this change could result in complete license activation failure, so it must be factored into upgrade planning.

6. Legacy Products and Special Edition Support Status

Let’s also review support status for legacy XenApp/XenDesktop versions and other legacy products that preceded the CVAD rebrand.
