SECURE DIGITAL WORKSPACE
To help you plan and prepare for your maintenance and support needs, this page describes the key milestones and support policies in the product lifecycle for Citrix XenServer.
The date that signifies when a new product release may be ordered and fulfilled in all applicable languages, discount programs, delivery methods and worldwide geographies.
With GA of a new release, some applicable offerings of the previous release will be phased out:
The date on which Citrix publicly communicates the specific dates for a product's End of Maintenance (EOM) and End of Life (EOL). This information is posted within the Product Matrix or Legacy Product Matrix tables. For new products, status change dates will be communicated on the product’s General Availability (GA) date. The standard policy will set the EOM date a minimum of three years after the GA date, and the EOL date a minimum of five years after the GA date. In addition, Citrix will post an End of Sales (EOS) date at its own determination.
The date that signifies when a specific software or appliance release will no longer be available for purchase.
For the majority of Citrix products which incorporate a date based license model, the EOS date is generally not applicable since new connection licenses work with previous product versions. In the event that a product line under a date based license model is being brought through End of Life (EOL), there will be a minimum 90 days notice of the EOS date.
Citrix products that have been added to the portfolio via an acquisition, or have yet to transition to the date based license model, will typically offer a licensing method that associates connection licenses to the product version. In these cases, there will also be a minimum of 90 days notice of the EOS date.
The 90-day notice period gives customers the opportunity to purchase additional licenses to allow for growth while they plan for a version upgrade or deployment of a new release.
The date that signifies when a specific product release will have no further code-level maintenance other than security and critical updates. Code level maintenance is typically delivered in the form of Service Packs, Hotfixes, or Hotfix Rollup Packs. The release of a Service Pack or Hotfix Rollup Pack may define a new maintenance baseline for the product. Citrix customers may be required to upgrade to a Service Pack or Hotfix Rollup Pack to receive continued maintenance on the product. After the EOM date, technical support continues as before but code-level maintenance will be limited to security related issues and other issues deemed critical by Citrix. Security issues could be related to publicly identified security vulnerabilities, other security vulnerabilities or Microsoft’s publicly released security updates.
The date that signifies when security-related and critical hot fixes, technical support and product downloads will no longer be available. Technical support for other 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.
This milestone signifies when a specific product release will no longer be covered under the Extended Support Program. The Extended Support Program puts customers in control of their upgrade strategy by offering technical support and maintenance after the End of Maintenance (EOM) or End of Life (EOL) milestone, and is typically purchased in 6 month blocks. Refer to the Software Support Programs page for details on the Extended Support Program and other Technical Support programs applicable to this product.
