I am planning the upgrade of Forms  10.3.1 to 10.4.1.  I currently have several groups of users involved in forms development and promoting forms from the development forms server to the production forms server.  My plan is to upgrade the development forms server and allow a window for testing (two weeks) and then upgrade the production forms server.  Am I correct in thinking I will need to freeze the promotion of any processes to the production forms server until it has been upgraded to the same version.  What would happen if I attempted to push a 10.4 process onto a 10.3.1 server?  Does this apply to Workflow as well?
