Citrix XenApp and Windows Server support and End of Life timeline

Over the past few months I've had more than one conversation about how the product lifecycle for Citrix XenApp and Presentation Server doesn't jive with Microsoft's timeline for Windows Server 2003 R2.

Over the past few months I've had more than one conversation about how the product lifecycle for Citrix XenApp and Presentation Server doesn't jive with Microsoft's timeline for Windows Server 2003 R2. If this were true, it would be particularly alarming to people that have to be running XenApp 5 on Windows Server 2003 R2 or Windows Server 2008 (which nobody does or will do until support for 2003 R2 runs out). This is a fairly sizable portion of the community because many organizations still have apps that can't run on Server 2008 R2, which is the only OS supported by versions of XenApp from 6 on.

In an effort to quell some concerns and get all the information in one place, I thought I'd make a single timeline with all the important milestones on it. What follows is an attempt to visualize what's coming in the next few years. All the data is from the US, just in case there are are discrepancies between countries. Also, this is all publicly available information gathered from Citrix and Microsoft websites.

What's interesting to note is that Citrix has recently extended support of XenApp 5 and Presentation Server 4.5 beyond their planned dates so that they match the dates of Windows Server 2003's end of support. So, even though the End of Life (EOL) date for Presentation Server 4.5 and XenApp 5 is March 31, 2013, the product will still live in Extended Support until July 14, 2015, when Windows Server 2003 is finally retired.

During this time, there will be no further public patches and hotfixes. Rather, any patches will be one-off solutions that you have to acquire through support calls (although that process isn't new to many of us). 

Without further ado:

Thanks for compiling this in an easy to digest format, Gabe!  This has definitely been a point of consternation for many of our customers.  The upside is that it's pushing many to quit procrastinating on efforts to modernize their applications to be 64-bit / WS2008R2 compatible.


I've been trying to socialize the importance of the fact also that "Exetended Support" is not a free period of support - at least with Citrix, it's  a for-fee service.  I believe the same to be true with Microsoft.  I would view the extended support periods as an absolute avenue of last resort for most customers.  To be in a position of critical security patches only for a couple years sounds like a huge risk to me...
