Is Citrix XenApp 6.5 compatible with VMware 6.0 Update 3 (build 5050593)

We are preparing to upgrade our version of VMware.

Currently we are at VMware version 6.0 Update 2.
Planning to upgrade to VMware version 6.0 update 3.

I am researching to make sure different applications and equipment are compatible with VMware 6.0 update 3.  I have update the Citrix NetScaler program;but, I am  to sure how to research if our Citrix XenApp servers?

Question:  How may I check if Citrix XenApp Server 6.5 is compatible with VMware 6.0 Update 3 (build 5050593)

Citrix XenApp is an application which is installed on a server OS, so providing the Server OS in the Guest is compatible with ESXi 6.0 U3, there should be no issues.

e.g. Citrix XenApp does not really have any interaction with ESXi Host OS like XenDesktop

Apologies but the question is better stated as is this "operating system" compatible with VMWare X.X.

Unfortunately, this is a common misconception but please don't take that personal.  You won't really find anything from Citrix or VMWare relative to compatibility at the BOS (Bottom of Stack (my term))  which can range from VMWare, Hyper-V, Linux Foundation XenServer, and other hypervisors.  Same goes for physical hardware.


I need to be very precise here in that Citrix Netscaler has nothing to do with Citrix XenApp - beyond StoreFront integration and XenApp/XenDesktop ICA Proxy.  This sounds harsh but is honest.  You (I) can implement Citrix Netscaler to replace F5 BigIP.  With or without XenApp.

With Edition ADC, I can host 3000 websites on a single IP Content Switch, Layer 7 Firewall, and load balance every server in the environment from LDAP to SQL.  (one small example)

However, Netscaler is Unix Open BSD, so you should validate the "Firmware" level of Netscaler relative to your Hypervisor version.

XenApp/XenDesktop run on Microsoft Windows Operating System.  If your running 2008R2, 2012R2 for example - the common mistake is licensing for Data Center instead of Standard Edition because unlimited virtual doesn't apply to VMWare and nor should it.

If you scale horizontal with XenApp, 4 vCPU (or 2) and 32 GB RAM (or16) is sufficient.  Server standard license is 1/3 the cost.  

Citrix licensing is concurrent, I have a good article on how to save a million dollars (or more, here).  By article, I mean my reputation on the and "been there done it".  Many Many times.  I'm a "pattern" person.  When I find a pattern that is repeatable and works every time - great!

Where I try to differ is now that that known pattern and make it better, save more money, get more guests per host, more applications per XenApp image, hit a 6 cents per hour cost per user and 10 second less login.  Striving for 3 second.


I published this some time ago and been amazed at how many people have not only not questioned it, but flat out ignored it.  That link right there is how I get past recruiters, sometimes.  Getting very hard.

Look, Citrix is TOS (top of stack).  It is not an OS, it is not an application.  Absolutely not.

It is a framework and a protocol.  Like the first Mad Max movie with Mel Gibson with the "blower" and Nitrous.  If you have no idea what I'm talking about, just look at this picture:

Custom job.  Ford Falcon XB GT Coupe 1973 "V8 Interceptor"

Maybe not the best analogy but you know RDP, so take RDP and add some custom/proprietary things and you get ICA and to now FMA (unless it has changed?).

And none of it matters, if you cannot drive the car (Architecture and Design).

Add HA, two gas tanks, other tweaks (Policies), Netscaler is still out o the picture.

Cost? What are you paying for? is it FMA over RDP, FMA or PCoIP?


Depends on the licensing but with Platinum you get everything that no one uses or implements; APPDNA, UPM, Citrix Profile Management, Monitoring (as it pertains to properly configured Citrix Director with advanced reporting and all the feature sets enabled), StoreFront, License Server, and the list goes on.

What do you really get?  You get the best current known solution for accessing any internal hosted application from any device and any location that has at least a 14KB modem.  And Netscaler pretending to be only a Secure Gateway.

Which if not mistaken, is free now.  

Add on StoreFront, Unified Experience, properly configured Citrix Policies, correctly configured load balance profiles, user profiles, Global Load Balancing and now you quickly have ACTIVE/ACTIVE data centers with routing based on closest proximity?

APPDNA, can analyse a workstation or server, all the applications, spew out a report of what developers or third-party needs to fix for that application to work right in 2008R2, 2012R2, 2016 running RDS..... And yes, Citrix is even optional.

You import your core OS(S), real world use case application scenarios from Windows XenApp on 2008 (FOR example) and it will rate the application 1-5 in complexity to migrate to 2012R2.  Then, do it again with one click to migrate it to 2016.  Operating System, applications.

Quote (me)

"Citrix is a conduit for the business application that is secure in that no data exists or transverses the connection, only keystrokes and screen refreshes that leverages a combination of Secure Gateway, Secure Ticket Authority, and XML to eliminate man-in-the-middle attacks.  With Netscaler supports TLS 1.3 (latest Firmware), terminates sessions on 443 at minimum RSA 256 and 2048 bit key (minimum), reverse proxies sessions (which have no data) to a load balanced farm of servers that if running on Provisioning Server and configured correctly - ? TFTP HA ? DHCP HA ? provides local HA and if local site goes away supports full ACTIVE/ACTIVE GSLB across multiple locations and those components support Clustering (Netscaler), and it comes in color FIPS-2 compliant as well"

Hopefully, that is a good quote.

Hello Mr. Murphy.  

Your information was interesting; but, a bit too much.  The actual answer to my question was from Mr. Hancock.

Thank you for the information everyone.

I agree, too much for some too little for others.  I don't have much spare time and when I give back I try to use a style that teaches not just answers.  Knowing that others might read this and appreciate the fundamental understanding of the answer is... and this is why.... This is my style of answering questions.  

I respect your response and question answered and the purpose of this forum is your right to award the most appropriate answer.  

Actually, when I initially answered I did not see Andrew's response and it was not my intent to provide duplicate response so my apologies Andrew.
