In the process of upgrading to 5.1.50 directly from 5.1.48 on beta.ine.uaf.edu. I ran into some difficulty on that as the machine ran out of disk space. Spent some time talking to Peter about short and long term solutions. A plan is in order.

The actual process of upgrading 5.1.50 went well on the beta machine. Will try it tomorrow on the production server.
