Does Workflow Manager 1.0 support in-place upgrade of the operating system? We have an ongoing effort to retire all of our Windows 2008 servers, and I'm trying to determine if it's possible to perform an in place upgrade of the OS from Win2008 to Win2012 R2. Our workflow manager instance is hosted on a dedicated server, outside of the SharePoint farm. If needed I can build out a new server running 2012, but I'd like to just upgrade the existing server if it's possible. I can't seem to find anything about this online. Thanks.
