When upgrading a system with separate clients and servers, the recommended strategy is to upgrade the clients before the servers. If you must upgrade the servers first, we recommend using Server Emulation on the servers to ensure client compatibility during the upgrade process. If you do not use Server Emulation to advise clients of the server's object versions to save, then it will be possible for later version clients to save mimics and other objects which are then not compatible with the older clients communicating to that server. See detailed upgrade instructions for your version.
