.. _Detector Server Upgrade:
Upgrade
========


**Location:** slsDetectorPackage/serverBin/ folder for every release.

.. note :: 

    For Mythen3, Gotthard2 and Eiger, you need to add scripts to automatically start detector server upon power on. See :ref:`Automatic start<Automatic start servers>` for more details.

 .. note :: 

    Eiger requires a manual reboot. Or killall the servers and restart the new linked one. If you are in the process of updating firmware, then don't reboot yet.
