Question
At the moment we have 2 hosts with winfm attribute. Can we safely remove the old host?
Answer
Yes. It is safe to remove it. OA will redirect requests only to a server with WebFileManager service installed.
If you want to keep the server in OA, but disable File Manager on it, remove the WebFileManager package from this server. If you want to remove File Manager from NG web server/cluster, please refer to the following article:
