VMware: How To Rollback ESXi 4.1 to 4.0 Upgrade

Sometimes it is necessary to rollback an installation of VMware ESXi, reverting to a previous installation. Last weekend I did this for testing in my home lab. It’s pretty easy…

image

^ My upgraded VMware ESXi 4.1.0 Build 260247 server

 

image

^ Reboot the host and press SHIFT + H to revert the rollback. Message:

Current hypervisor will premanently be replaced with build: 4.0.0.-164009. Are you sure?

Press Y (or SHIFT + Y) to rollback the upgrade

image

^ Oke.. 2 seconds later I received this message:

1 log messages, press ESX to view.

 

image

^ Message:

Fallback hypervisor restored successfully

 

image

^ The ESXi 4.1 host is downgraded to ESXi 4.0.0 and is back online again 🙂
