Upgrading a Host
After you've created a host upgrade baseline, you can use this baseline to upgrade an ESX/ESXi
host following the same basic sequence of steps outlined previously to remediate other vSphere
objects:
1.
Attach the baseline to the ESX/ESXi hosts that you want to upgrade. Refer to the previous
section “Attaching and Detaching Baselines or Baseline Groups” for a review of how to
attach a baseline to an ESX/ESXi host or several hosts.
2.
Scan the ESX/ESXi hosts for compliance with the baseline. Don't forget to select to scan
for upgrades when presented with the scan options.
3.
Remediate the host.
Back Up Your Host Configuration as Required
Unlike with previous host upgrade methods, VUM no longer supports rollbacks after a problematic
upgrade. Before you start the upgrade, make sure you have su cient information about the state
of the host to restore or rebuild it if necessary.
