Changing Host Types

Changing host types from ESX to ESXi (or ESXi to ESX) have no in-place upgrade, but you can migrate existing
virtual machines and datastores or perform an in-place, fresh installation to replace one host type with another.

Change ESX to ESXi Installable
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.
Procedure
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
n
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
n
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.
Change ESXi Embedded to ESX
You might choose to replace ESXi Embedded with ESX.
Prerequisites
You must have an ESXi Embedded host. An ESXi Embedded host is a physical server that contains an ESX
image preinstalled as firmware in the factory or burned onto an external USB key.
