ESX 4.1 with vCenter 4.0

[jvchandoo]

We are planning to upgrade from ESX 3.5 update 4 to ESX 4.1. At this time we don't want to upgrade vCenter 4.1. Is this possible to just upgrade ESX hosts and not the vCenter host?

No, you need to upgrade to vCenter 4.1 first. vCenter 4.0 doesn't support ESX(i) 4.1 hosts.

ANY time there is a ESX release, it's always a good idea to update vCenter. vCenter must be the same or higher version than the ESX it manages, but the ESX host cannot be newer than vCenter.

True, unless you have a product (other that ESX) tied to vCenter that isn't supported on the latest update. i.e. View.

vCenter must be the same or higher version than the ESX it manages, but the ESX host cannot be newer than vCenter.

False. While ESX 4.1 requires vCenter 4.1, ESX 4.0 U2 is fully supported under any version of vCenter 4.0.

False.

No it's NOT. 4.0 U2, but he specifically states 4.1

Things fuzzy on your screen?

Well, what about ESX 3.0 and 3.5 supported by virtual center 2.5? check the following link

No it's NOT. Page 3, what does it say? vCenter 4.0 does NOT support ESX 4.1.

After adjusting your monitor, why don't you read what I actually wrote. Then, read what you wrote.

You made a generalized statement ("ANY time"), not specific to ESX 4.1. That is simply wrong. While I agree it is generally a good idea to keep vCenter ahead, it is not ALWAYS required.

That document is the bible. Follow it and you'll be in good shape.
