I am planning my upgrade of RIO 10.3.1 to 10.4.1 and need to confirm the order of installation as I will be rolling the upgrade over several weeks from my development server farm to the production server farm. I am thinking I would need to upgrade the Directory Server first (this is shared by both the Dev and Prod environments) and then upgrade the LFS Server, Clients, Forms, Workflow, etc. Is there documentation to support upgrading a distributed environment (separate Dev and Production servers for each major component)?
Additionally, will I need to upgrade all Directory Server Web STS instances to 10.4 at the same time I upgrade the directory server?
