I am upgrading my vSphere environment from ESXi 4.1 to 5.0. I am trying to decide if there are any advantages to doing a fresh install vs a simple upgrade. Is there an advantage to the new GUID partition tables over the old MSDOS based partition tables?
How would I go about doing a fresh install and restoring my config? I know the configs are quite different from 4.1 to 5. Can I just take a backup of my 4.1 config, do the fresh install of 5, then restore the backup and it will be upgraded to work on 5? Or would I have to reconfigure it manually?
