[quote:54373d93e4=“ese-aSH”]you should rather use the designer SDK.

Actually, the Designer SDK is likely the only way. The universe is stored on the filesystem, so I am highly skeptical that any enterprise SDK would reach “inside” a universe to make changes. The universe description that you were updating is likely just the name that displays in Infoview (updatable via CMC).
You might consider this utility, designed using the Designer SDK for the specific purpose of updating object names and descriptions.
