You might choose to replace ESX with ESXi Installable. The method you use for performing this task depends on whether you need to preserve VMFS datastores.

If you install ESXi Installable on the same disk where ESX is installed, ESXi overwrites the VMFS datastores on the disk. To prevent this, you can migrate virtual machines from an ESX host to an ESXi host.

1

Choose a method to replace ESX with ESXi.

If you do not want to preserve the virtual machines on the datastore, install ESXi on the disk on which ESX is installed.

ESXi writes over ESX.

See the Setup Guide.

If you do want to preserve the virtual machines on the datastore, migrate virtual machines from an ESX host to an ESXi host .

See Basic System Administration.

2

Use the vSphere Client to reregister the virtual machines on the ESXi host.

See Basic System Administration.
