What does this mean for you ? As this is a major upgrade we cannot guarantee that jobs that are in a non-final state will survive, though we will try. The upgrade will proceed in the following order: - Server upgrade - Web interface upgrade - cvmfs UI upgrade - cloud interface (in case of problems only) v7r3 is a python3 release. For backwards compatibility we will maintain a python2 UI on cvmfs as well as a python3 UI. If you are maintaining your own DIRAC UI you should try to upgrade soon thereafter, though the old UIs will probably keep working for quite a while. Instructions will be supplied nearer the time. Please let me know if you have any questions and/or if this date is the worst possible date for the upgrade we could have picked.
