FAQ: Is it possible to load a zenon project of a previous zenon version in a newer Service Engine version?
The zenon Service Engine like the engineering system offers a compatibility feature. This means a Service Engine of a newer product version is able to load projects of an older version. This is especially used in zenon network projects, where dedicated Service Engine clients can have a newer version than others. This helps e.g. during the updating process as Service Engine Clients can be updated step by step depending on the time slot available. It is not necessary to update all clients at once.
However it is recommended that servers are always updated to the latest version and that both servers are running the same zenon version.
