Migrating a Citrix XenDesktop Environment to a New VMware vCenter Instance

Introduction

Recently we ran into a situation where a customer had requested an upgrade to their existing VMware vCenter from version 5.1 to 5.5. Upon reviewing the existing vCenter server, we noticed both VMware SSO and SRM were being used on the same server. Based on VMware best practices, we recommended separating vCenter, SSO and SRM to three distinct servers. The migration of the services to the three new servers worked without any issue. However, the existing Citrix XenDesktop environment was pointing to the old vCenter instance. Unfortunately Citrix doesn’t make it easy to simply point to the new vCenter instance.

Solution

The Citrix XenDesktop 5.6 environment was using Machine Creation Service (MCS) along with Personal vDisk (PVD) features. Both features integrate heavily into the virtual infrastructure, in this case VMware vCenter. To resolve this issue, Gotham created new virtual desktops based on the new vCenter instance. We then followed http://support.citrix.com/proddocs/topic/xendesktop-7/cds-manage-personal-vdisks.html to back up and restore the PVD’s to the new virtual desktop. The PVD migration could only take place when the user was logged off, as the PVD was locked. Following the backup and restore of the PVD, we simply disabled access to the old virtual desktop and enabled access to the new virtual desktop.

Summary

Overall this was a tedious process even given a small XenDesktop implementation. If this was a much larger deployment of XenDesktop with PVD this would have been a major issue.
