available disk space before an upgrade

Symantec Endpoint Protection Manager
installation requires a minimum amount of available disk space. Make sure that any current servers or new hardware meet the minimum hardware requirements. However, additional available disk space may be needed during an upgrade to allow for the creation of temporary files.
Make a backup of the database before making configuration changes. See:
Tasks to increase disk space on the management server
Change the LiveUpdate settings to reduce space requirements
  1. Go to
    Admin > Servers
    and right-click
    Local Site
    . Select
    Edit Site Properties.
  2. On the
    tab, reduce the number of content revisions to keep. For an upgrade, you can lower the setting to 10. Allow time for
    Symantec Endpoint Protection Manager
    to purge the extra revisions. However, the reduction of revision numbers may trigger full update downloads from the clients that check in. An increase in these full update requests may negatively affect network performance.
    Returning the revision setting to its previous value after the upgrade completes is not necessary. Improvements to the way
    Symantec Endpoint Protection Manager
    stores and manages content means that a larger number of revisions takes up less disk space than in earlier versions.
