Appendix: Migrating From Flash
Storage to Hard Drive Storage
Overview
Citrix and Dell have decided to retire the embedded OEM Dell editions of
XenServer, as of XenServer 5.6 Feature Pack 1. For this release, only the
hard-drive installed retail edition of XenServer is available. If you are running
the Dell OEM edition of XenServer 5.5 or earlier, you can upgrade to
XenServer 5.6 Feature Pack 1, preserving all of their virtual machines and
configuration data.
Pre-requisites
• Upgrade to XenServer 5.6 Feature Pack 1 is only possible from XenServer
5.5 (with or without update 1 or update 2). If you are running an earlier
Dell edition, you must upgrade to XenServer 5.5 Dell edition before
upgrading to XenServer 5.6 Feature Pack 1.
• Before upgrading or updating XenServer, it is recommended that you
backup the virtual machines that are associated with the host or resource
pool. For more information, see
XenServer 5.6 Feature Pack 1 Installation
Guide
at mycitrix.com .
• If you are currently using a
Dell edition of XenServer installed on a USB
flash media, you must install hard drives into their systems. The retail
version of XenServer does not support installation to a USB flash media, as
it does not incorporate the various disk traffic reduction measures.
• If you are installing XenServer 5.6 Feature Pack 1 on a hard drive, there
must be a minimum of 8 GB of free space on the drive. If there is
insufficient free space, you must export one or more VMs that are stored
on the local SR to other storage, before upgrading to XenServer 5.6 Feature
Pack 1. If XenServer is installed on the hard drive, additional space is not
required as the new version of XenServer replaces the existing version.
