Following previous notifications to End of Maintenance last year, Citrix has announced that versions 12.0.x of the Citrix ADC (formerly Citrix NetScaler) operating software will go End of Life as of 30th October 2020.
What does End of Life mean?
End of Life is the date that signifies when technical support and product downloads will no longer be available. Technical support for issues will be limited to information contained in the Citrix Knowledge Center and Support Forums. If the issues cannot be corrected through this method, then an upgrade path or migration to the latest version or product replacement is recommended.
What action do I need to take?
If you are still running version 12.0.x, Citrix recommend you take steps to upgrade to the latest 12.1 version of the Citrix NetScaler ADC operating system to take advantage of the advanced features and fixes. This will ensure best service coverage over the life of the product. Official guidance also suggests you can downgrade to 11.1. Unlikely but possible. Below is a snippet from the Citrix Support Knowledge Center
For MPX/SDX, download the latest GA 11.1.x or 12.x releases of the Citrix NetScaler ADC firmware.
For VPX, download the latest GA 11.1.x or 12.x releases of the Citrix NetScaler ADC firmware.
Please check the Citrix Downloads site for the most current firmware build.
By downgrading to 11.1x you may inadvertently remove some features within 12.0.x that you are running in production, so our advice is to upgrade to the latest 12.1 or 13.0 builds, but again, proceed with caution as some of the older configuration commands, particularly around the Gateway functionality have depreciated in 13.0. If in doubt, shout! We can take a look at your config and advise as to the best course of action to limit disruption to your services.
