Server manager state backward compatibility
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
We should try to ensure that the server manager state files can maintain backward compatibility. One big problem we have had with ParaView state files is that they become invalid any time ParaView is updated.
At a minimum, the state file needs to save the version of ParaView that created the file. That way future versions can make adjustments accordingly.
It would also be good if ParaView did something intelligent when errors are encountered from reading the state file, which can happen if the server manager definition files change unexpectedly. However, we can probably defer that to the next version of ParaView when there will actually be an issue with backward compatibility.
