Upgrade ESX 3.5 U3 to 3.5 U5

Hi all,

I have a ESX Server running 3.5.0 U3. I have to upgrade it to 3.5.0U5. I have downloaded the upgrade package (zip file). I want to do this from command line.

I did google it up but not sure if below command will work

esxupdate --bundle <upgrade.zip> update

Also I need to know if how can I revert to U3 from U5 if things do not fall in place from it from command line. This is a DEV Server with no VM’s on it. I do not want to go for a fresh installation.

Appreciate your help on this

Thanks
