Before I do an upgrade of my existing ePO environment form 4.0 to 4.5 I was reading some documents.
The download from McAfee is telling me this:
ePolicy Orchestrator 4.5.0 Patch 1 Setup. This release may be installed where no previous version of
ePO has been installed, or can be used to upgrade existing ePO 4.5, 4.0 or 3.6.1 installs. See readme
But the readme is telling me this:
CAUTION: McAfee does not support automatic upgrading of a pre-release version of this software. If you are
running any previously released version of the McAfee ePolicy Orchestrator 4.5 software in your environment,
you must uninstall before installing this version of the software.
It is or it is not possible to upgrade ePO from 4.0 to 4.5 without uninstalling the existing installation?
Yes, you can upgrade form 4 to 4.5. "Pre-release" in this context means beta - so you can't upgrade from a beta version of 4 or 4.5.
