Compatibility: Upgrading servers from ESX 4.0 to ESXi 4.1.U1.

Hello again,

I'd like to get some clarification regarding compatability.

In particular, upgrading servers from ESX 4.0 to ESXi 4.1.U1.

Are there any compatability issues with the above upgrade relative to:

  • vMotion

  • Fault Tollerance

  • High Availability

We're wanting to ensure that what we have isn't going to go pear shaped after we start down the upgrade path and lose the ability to use any of the above.

Cheers,

Cameron Young

It should make no difference.

Just make sure you read the upgrade guide, take all the required precautions such as backing up your database and don't rush it. Smiley Happy

Direct Upgrade the system from ESX to ESXi is not supported. you have to follow the migration steps http://www.vmware.com/products/vsphere/esxi-and-esx/

All the functionlality that you have listed will work perfectly in ESXi4.1U1 as well. Make sure that you followed above procedure. Also make sure that you upgrade the vCenter Server and Update manager to 4.1U1 before you start ESX migration to ESXi.
