Citrix Virtual Apps and Desktops 1912 LTSR announced – Watch out when you upgrade!

On Wednesday, Citrix announced the latest Virtual Apps and Desktops Long-Term Service Release (LTSR). As always, there’s much to discover in the new milestone release. This time, there’s also a major caveat.

To upgrade Virtual Apps and Desktops to the latest version, you need a licence file with an eligible Subscription Advantage (SA) date, which is available from the licence portal. What’s different now is that—compared with previous licence files—this one looks suspiciously empty.


So why is that? Because Citrix purged the old V2 licences from the file. These licences are required to unlock legacy products such as XenApp 6.X, but also current products such as Provisioning Services (PVS).


Important: Good monitoring.

When you deploy the file on a licence server, this will effectively un-licence products attached to your Virtual Apps and Desktops licence, such as PVS.

The PVS server will then start the clock on the 30-day grace period, which you may not even notice unless you have some very tight monitoring in place. In other words, there’s a real risk you may inadvertently lock down your environment.


Unfortunately, the 1912 LTSR licence server was not adapted to properly handle the new licence file. Our advice: Make sure you know what the upgrade will do to your environment, stay vigilant when you deploy the latest licence files and do not hesitate to get in touch with us. We’re always happy to help!
