Since this is a CET version, we expected to see a “few more problems” than after an “ordinary” software upgrade. But we were surprised that all applications run very smoothly. The new features are great, improving workflow. Today is the first clinical day after the upgrade, 120 patients are treated without any problems. Yesterday (Monday) was reserved for upgrade and training. But actually the upgrade was finished and verified already on Sunday. So we could have started as well on Monday morning, 7:00 a.m.
