I'm currently upgrading 2 customer's UCM Cluster's, one is a 6.1(3) and the other is a 5.1(3). I had no issue with the upgrade from 6.1(3) to 7.1, but I'm getting an error from the 5.1(3) cluster when trying to upgrade. These are the same DVD's that I used for the 6.1(3) cluster I upgraded last night and another customer 2 weeks ago. Here's the message:
The directory was located and searched but no valid options or upgrades were available. Note, a machine cannot be downgraded so option and upgrade files for previous releases were ignored.
