How to rename a Domain in an Utility Network

[SanchezNuñez]

Good afternoon,

What is the way you recommend to rename a Domain in an Utility Network. The domain is a regular domain imported from a GN, not a UN domain related to assettypes.

Let say that the domain name is  called  DmMunicipality, and we want to rename it   UNDmMunicipality.

Thanks

@SanchezNuñez - I haven't had any issues renaming domains using the Domain View.
I haven't found any issues with this in the past.  
If you wanted to play it safe - you could always - create a new domain and assign it to relevant fields. 
You can use the Domain to Table tool to extract the domain and then Table to Domain Tool to add the add the domain.

Good morning @gis_KIWI4 

Were thee domains linked to Utility Network feature classes?

thanks

@JoseSanchez - No they weren't.
The original question is specific to non-UN attributes.
