UN Version Downgrade

[JohnGoat]

I have data model with UN 6 version.
How can I downgrade this Data model to UN 5?

I don't believe you can. The only way I know of is to use a version of ArcGIS Pro that supports UNM V5 as its highest version. You'll probably need ArcGIS Pro V2.8/2.9

Hi,

I tried this with version 2.9.6 and it didn't work.
