Are Icons stored in choice fields in record producer part of update sets in ITSM

[Ro1]

Icons are stored in choice fields in the record producers. Are they part of update sets when we move from one instance to the other ? or do they have to manually imported ?

Thanks

Yes, generally they are part of the same update set, but sometimes we need to move them manually if they are not reflected properly.
