	When the FRM-2 neutron source went into operation (2002) and many instruments were moved from the closed-down Jülich reactor to the new facility, it was agreed on a choice of front-end hardware and the TACO middleware from ESRF. To keep up with software standards, it was decided recently to switch to TACO's successor - the TANGO control software. For a unified "user experience", new graphical user interface software "NICOS-2" is being developed by the software group at FRM2. While general semantics of TACO and TANGO don't look very different at a first glance, and adaption of device servers seemed to be straightforward at first, various problems in practical operation were found. The problems were due to differences in state handling, timing behavior and error reporting. These problems, and the changes that had to be made to ensure reliable operation again, will be described.

Forschungszentrum Jülich has been operating the neutron Instrument DNS at the neutron source FRM II for about 10 years. DNS is a time of flight neutron spectrometer with polarization analysis that experienced a major upgrade in 2014 and 2015. During the upgrade DNS was equipped with new electronics and a new control and data acquisition system, including a transition from the existing TACO system to its successor TANGO. On the client side the NICOS software developed at FRM II is used for the implementation of measurement operations and user interface. The design of the new control and data acquisition system is presented and the lessons learned by the introduction of TANGO are reported.
