Installation guide

ESX
For ESX, the upgrade reuses the existing /boot partition to hold the ESX 4.1 boot files.
For upgrades from ESX 3.5 to ESX 4.1 using vCenter Update Manager, the ESX 3.5 installation is mounted in
the new ESX 4.1 installation under the /esx3-installation directory after the upgrade.
The upgrade to ESX 4.1 preserves almost all configuration data, including your networking, security, and
storage configuration. Specifically, the upgrade to ESX 4.1 preserves the following files from the ESX 3.5 files
system and in ESX 4.0 it preserves all the files which are mentioned below excluding kerberoes configuration
(/etc/krb.conf,n /etc/krb.realmsn, /etc/krb5.conf).
