I have a C350 running on 6.0.0-745 and just received a second box to make a cluster. The new box runs on version 5, but can't get upgraded to 6.0.0-745. 6.0.0-746 or 6.0.0-747 are the only choices. Is there a way to get the 6.0.0-745 image? I can't update the box that I have, because this would mean downtime of my email services.
Any help would be appreciated.
