Upgrading Windows with Infor OS installed

Infor does not recommend and cannot support in-place upgrades of Windows OS with Infor OS installed.

If you must up-version the operating system, we recommend that you provision a new server to host Infor OS and expand your existing farm. Once complete, you will be able to decommission your old server.

Prerequisite: Infor OS must be installed using an alias.

Recommended steps:

1. Provision a new server to host Infor OS.
2. Install Infor OS on the new server pointing at the existing installation.
3. Promote the new server to the primary Infor OS node.
4. Uninstall Infor OS from the original server.
5. Update the Elastic Search YML file on all hosts of Infor OS. Refer to the "Updating the Elastic Search YML file" section in the Infor OS Installation Guide for instructions on how to update this file.
