Best Practices for Citrix XenApp Hotfix Rollup Pack Installation and Deployment
This article introduces and discusses some of the best practices for installing and deploying hotfix rollup packs for XenApp and Presentation Server. Citrix periodically releases hotfix rollup packs that might include bug fixes, security fixes, and enhancements for all currently supported XenApp versions. Citrix recommends that you install the latest hotfix rollup pack to get the best out of XenApp in terms of performance, security, and overall user experience.
For a major XenApp release, Citrix supports the most recent Hotfix Rollup Pack (HRP). In addition, Citrix supports the Hotfix Rollup Pack released prior to the most recent hotfix rollup pack for 12 months provided the requests are commercially viable. However, public hotfixes for security vulnerabilities are provided only for the most recent hotfix rollup pack.
For example, Hotfix Rollup Pack 02 for Citrix XenApp 6.0 for Microsoft Windows Server 2008 R2 was released on 12/06/2012 and is the most recently released hotfix rollup pack for Citrix XenApp 6.0 for Microsoft Windows Server 2008 R2. The hotfix rollup pack released prior to Hotfix Rollup Pack 02 was Hotfix Rollup Pack 01. In addition to supporting Hotfix Rollup Pack 02, Citrix will continue to support Hotfix Rollup Pack 01 until 12/06/2013 at which time Hotfix Rollup Pack 01 is considered End of Life.
