Yes we know the procedure of the downgrade. The nice thing of the upgrade is that the VR names stay as is and we thought it would be nice if this would also be possible while "downgrading" or more precisely, state="your VR are not in a version the running ACS supports --> recover them" The thing is with "destroyed VR" hey are not coming back automatically, do they? They are only be recreated on a e.g. network restart or an api call related to a VR (user VM stop/start, etc.) right? Regards René
