The purpose of the downloadable document below (SMS3.3to5.1upgrade.pdf) is to point out several items that can affect the successful upgrade of the Intel® AMT™ Add-on from version 3.x to Intel® Client Manageability Add-On for Microsoft* SMS 2003 v5.1.
Upgrading the Add-on from version 3.x to 5.1 is relatively straight forward. The document I've created identifies several potential issues that I have found that can make an upgrade change from relatively easy to an upgrade that makes you wonder if you can find your backup documentation. You do have your documentation, right? It is not meant to be all inclusive, merely to point out those items that could be stumbling blocks.
Also, I have included a few screenshots of the installation process to help identify some messages that appear to be more alarming than they are meant to be with explanations as well.
For more detailed information about the installation, console operations and troubleshooting procedures, please refer to the latest documentation located at the Intel® Client Manageability Add-on for Microsoft* SMS 2003 download website the Intel® vPro™website and the Intel® vPro™ Expert Center.
