When importing the Operations Manager appliance using vCenter 4.0 or earlier, the process fails with the following error message:
Unsupported element 'ExtraConfig'
vCenter 4.0 and earlier lacks support for specific attributes of the Operations Manager appliance, and therefore importing the appliance fails as these attributes are unknown to vCenter.
Contact VMTurbo Support to receive a customized version of the appliance which is fully compatible with vCenter 4.0 and earlier, or, upgrade to the latest version of vCenter.
This article applies to Operations Manager version 3.2 or later.
