Upgrade to ESXi 4.1

[jenuster]

So I've done the google search but just wanted to see if anyone has migrated from ESX 4.0 to ESXi 4.1 and their experiences.

Initially I was going to just upgrade to ESX 4.1 but then I figured it would probably make sense to migrate to ESXi 4.1 under the assumption that it would make it easier to upgrade to the next release of ESXi (5.0?)

Me, me, I know the answer!
You can't upgrade ESX to ESXi. You need to reinstall.

If you have a clustered environment it's fairly easy to install ESXi and migrate the VM's if you have the opportunity to go that route, meaning remove a host or two from the cluster and install ESXi and migrate.

Yeah..we do rolling upgrades/reinstalls and usually can do it with no downtime.
