Failed to Import Upgrade: Release not Supported

[ttrulis]

Upgrading ESX 3.5 U4 to ESX-4.0 via Update Manager upgrade baseline.

File Name: ESX-4.0.0-update01-208167.iso

Error was: Upgrade release not supported by this version of VMware vCenter Update Manager.

I don't see a way to download any earlier versions. Any ideas?

Thanks,

you need to have the most current build of VUM that comes with the vCenter4 bundle to upgrade your ESX Hosts.

VMware vCenter Update Manager (build 208126)

Thanks that worked - must have been the build.
