                      light source plays an important role for the design of its
                      upgrade to PETRA IV. The PETRA III tunnel is made of
                      individual segments that move against each other. Here, the
                      long-term drifts of the tunnel ground that are mostly
                      introduced by temperature variations, are of the highest
                      concernfor the PETRA IV alignment tolerances and orbit
                      stability. This paper studies the evolution of the beam
                      orbit and corrector magnet currents over several years in
                      order to identify locations of misalignment in relation to
                      the mechanical movement between tunnel segments.},
