Installation information

Upgrading to this release requires preparation and an understanding of how the upgrade process works.

Before beginning the upgrade:

  • Review the upgrade information in the McAfee Enterprise Security Manager 11.2.x Installation Guide.
  • Make sure that your current McAfee ESM version is 10.2.0 (or later).
  • If you are upgrading from version 10.x, make sure all needed ports are open on your network (see the ESM Installation Guide for a list of needed ports).

After completing the upgrade

After the upgrade, you might see numerous messages in the messages log related to snowflex and snowman processes. These messages do not indicate a problem and will not impact system operation. They will eventually stop.

Before logging on for the first time, clear your browser cache. Not doing so might cause issues when you log on.
