To LTSR or not to LTSR? Citrix Releases Compared and Explained

LTSR-vs-CR--Which-is-right-for-youThe last Citrix LTSR (1912) was released in December 2019. And although this will be supported until 2029, many new Citrix features are being released for cloud first. This essentially leaves businesses deciding between the security and longevity they get with the latest LTSR Vs the agility and modernisation of the cloud-based CR route.

So, which is best for your business? In this feature, we break down the key elements of both LTSRs and CRs to find out which route you should be taking.


What is the difference between a Current Release and a Long Term Service Release?

Citrix Long Term Service Releases (LTSR) typically come out once every two or three years and are targeted for use in industries that tend to require a long test or certification process before deploying. While this slows the pace at which you can take advantage of new features, it offers a predictable maintenance cadence for ongoing fixes in the form of Cumulative Updates.

Citrix Virtual Apps and Desktops Current Release (CR) typically has up to four releases per year and gives on-premises customers access to new functionality and feature updates on a regular basis. On the other hand, the supportability period is shorter, so this means more frequent upgrades.

But it’s not just a matter of update regularity. Current Releases combine new technology and fixes in the one release. Long Term Service Releases contain components and features that are already well established and therefore trusted – especially by large enterprises with complex environments.

Fixes for Current Releases are more often than not released in the next Current Release. Long Term Service Releases will have a regular cadence of Cumulative Updates that will typically contain only fixes, not new features, or functionality.


What are the benefits of an LTSR?

  • Extended Lifecycle with support for up to 10 years. Citrix typically provides 5 years of mainstream support and 5 years of extended support for their LTSRs.

  • Predictable maintenance thanks to scheduled cumulative updates.Citrix releases cumulative updates for their LTSRs which are fixes devoid of any new features – making it easier to schedule on-going site maintenance while lowering risk to your deployments. Any new CU will include all fixes released in previous CUs for that component.
  • Reduced IT costs with simplified management.Opting for a Long Term Service Release will give you access to product releases along with a predictable maintenance schedule to help reduce uncertainties and mitigate risks.


What are the benefits of a CR?

  • Regular new features.  The fast pace of Current Releases means that businesses have access to the latest features helping to work and deliver their services in the most agile way possible. This also means you have access to the latest security, productivity and collaboration features.
  • Faster delivery of enhancement requests.  Faster delivery cycles mean that new features that address your enhancement requests become available more quickly.

Citrix Current Releases have 6 months to reach End of Maintenance and 18 months to run their total Lifecycle.

Which one is right for my business: LTSR or CR?

Long Term Service Releases (LTSR) are ideal for large enterprise production environments where you would prefer to retain the same base version for an extended period. With LTSR, you will have regular access to fixes but these are typically void of new functionality.

With each LTSR, there are new extended support timelines that let you plan for upgrades at a pace that is right for your business.

Current Releases are better suited for agile environments where you can rapidly deliver the newest app, desktop and server virtualisation features, including both production and test environments. On-going support and maintenance for Current Releases is aligned with the frequent release cycles.
