Installation instructions For information about installing or upgrading Policy Auditor, see McAfee Policy Auditor Installation Guide. Important: Ensure that you make note of the following points before you upgrade: purge data from previous inventory scan before upgrading. After the upgrade, we recommend you use Reset baseline for all inventory scan items. Due to the changes to the schema for the collected items, we recommend that you reset the baseline for scans of all items that are collected. CAUTION: If the reset baseline is not run at least once, the reporting queries and dashboards might have duplicate entries or the counts might not match for the collected items.
