B.2. Upgrading from version 3.2 to the current version

The following procedure describes how to install the current version of the XenServer Host over an existing installation of XenServer Host 3.1.

When upgrading from version 3.2.0 to the current version, be aware of the following:

any custom RPMs which you might have installed on the XenServer Host Control Domain will not be preserved
existing Windows VMs will need to have the paravirtualized device drivers reinstalled

To upgrade XenServer Host from version 3.2

Perform an orderly shutdown on the VMs hosted on the XenServer Host.
If any of your VMs are in the in the Suspended state, Resume them first, and then perform an orderly shutdown on them too.
Reboot the XenServer Host, and boot from the new version's Installation CD.
The installation script will identify the older version and prompt you whether you want to install over the existing 3.2 installation and preserve VMs. Select OK to proceed with the installation.
Follow the rest of the installation procedure as described in Section 3.1, “Installing the XenServer Host”.
Run XenCenter and connect to the upgraded XenServer Host.
To upgrade the drivers for a Windows VM, select the "Install Tools" menu option and open its console. Run the xensetup.exe installation program to upgrade your paravirtualized drivers. When finished, reboot the VM.
To upgrade the kernel and guest utilities for Linux VMs, follow the instructions in the XenServer Virtual Machine Installation Guide.
Repeat for all other Windows VMs.
