Installing, Configuring and Upgrading ESX Server

Upgrading from a Previous Version

of ESX Server

Before You Install ESX Server 1.5

There are a few steps you should take before you install ESX Server 1.5 to ensure the

best possible upgrade experience.

Resume and Shut Down Suspended Virtual Machines

If you plan to use virtual machines created under a previous version of ESX Server, be

sure they have been shut down completely before you upgrade.

If the virtual machine is suspended, resume it in the earlier release, shut down the

guest operating system, then power off the virtual machine.

Note: If you attempt to resume a virtual machine that was suspended under a

different VMware product or a different version of ESX Server, a message gives you the

choice of discarding or keeping the file that stores the suspended state. To recover the

suspended state, you must click Keep, then resume the virtual machine under the

correct VMware product. If you click Discard, you can power on normally, but the

suspended state is lost.

Commit or Discard Changes to Undoable Disks

If you plan to use existing virtual machines that have undoable disks, commit or

discard any changes to the virtual disks before you remove the release you used to

create them.

Resume or power on the virtual machine in the earlier release, shut down the guest

operating system, power off the virtual machine and either commit or discard

changes to the undoable disk when prompted.

Back Up Virtual Machines

As a precaution, back up the virtual machine files — including the .dsk and .cfg

files — for any existing virtual machines you plan to migrate to ESX Server 1.5.

Caution: The upgrade script used to upgrade from ESX Server 1.0 and ESX Server 1.1

to ESX Server 1.5 overwrites information related to sharing an Ethernet adapter

between virtual machines and the console operating system. If you are using this

functionality, you must set it up again after you upgrade. For details, see Sharing the

Console Operating System’s Network Adapter with Virtual Machines on page 226.
