We used a combination of SRG/eROSITA, XMM-Newton, and Chandra data to get a complete coverage of the Perseus cluster in X-rays up to R200c. While the Perseus central part represents a canonical cool-core structure with clear signs of AGN Feedback, the outskirts, in turn, serve as a convincing example of a merger-perturbed system. X-ray data seem to favor IC310 as the main galaxy of a subcluster that merges with Perseus. If IC310 is currently near the apocenter of the orbit its relatively small velocity relative to the main cluster can be expected.
