You can use Update Planner to run pre-checks and generate reports that provide pre-update information. You use this information to make sure that your system meets the minimum software and hardware requirements to ensure a successful upgrade of vCenter Server.

When you generate a pre-update report, Update Planner generates a list with actions that you must address to ensure a successful upgrade of vCenter Server in your environment. The report provides information about problems that might prevent the completion of a software upgrade or update.

  2. On the Updates tab, click Update Planner
  3. Select the target vCenter Server on which you want to run a pre-upgrade check from the list of available servers in your environment.
  4. Click the Generate Report drop-down menu and select Pre-Update Checks.
    The report displays in the bottom pane of the Pre-Update Checks panel.
  5. (Optional) Click Export in the Pre-Update Checks pane to save the report as a comma-separated values (CSV) file, which allows data to be saved in a tabular format.
  6. (Optional) Click Open Appliance Management to open the vCenter Server Management Interface, or Download ISO to download the selected ISO image with which to upgrade vCenter Server to the the selected target release.
