I am trying to upgrade an ESX 3.0.2 box to ESX 4.0. From what I have read I first need to upgrade the VIM. When I run the agent pre-upgrade checker I get an error at the ODBC DSN stating that I need to setup a 32 bit system DSN. In control panel of the windows 2003 server I see System DSN labeled vmware with drive of sql server. I am not sure what the upgrade checker is looking for. I am new to vmware so I am not really sure of what to do.
Thanks!
