Recommended fix High confidence

XenMobile Server 10.12 RP3 / 10.11 RP6 / 10.10 RP6 / 10.9 RP5 (depending on baseline version)

  1. 1. Identify the current installed version of XenMobile Server by checking the console or using the command line tool.
  2. 2. Based on the current version, identify the minimum required Rollup Patch (RP) version to apply:
  3. - For XenMobile Server 10.12.x: upgrade to RP3 or later
  4. - For XenMobile Server 10.11.x: upgrade to RP6 or later
  5. - For XenMobile Server 10.10.x: upgrade to RP6
  6. - For XenMobile Server 10.9.x: upgrade to RP5
  7. 3. Download the appropriate Rollup Patch from the Citrix support portal at https://support.citrix.com/article/CTX277457
  8. 4. Review the patch release notes for any prerequisites or specific installation instructions.
Caveat Standard Citrix Rollup Patch upgrade - minor version bump, review release notes for any configuration changes; recommend testing in non-production environment first
