iw123 thanks for links, it's really helpful.

But i want to know the possibility to do this in the first place with PowerCLI.

Because by unknown reason i don't have Upgrade Manager in my vSphere client.

I am not quite sure if you can use PowerCLI to update to ESXi 5.0, Alternativey you can vihostupdate to perform the upgrade

Check KB2004501 for the methods of upgrading

I have been done upgrade with help Update Manager plugin in vSphere client.
