using the Copy Paste from one fgdb to another. The orig attribute is type (double), the receiving fgdb has a coded domain for that field which is (long). We have the value of the CODE in the receiving gdb as the value in the orig data.
If we do this in arcmap 10.8 it works fine.
If we do this in ArcPro 3.1.2 it drops the coded value completely and gives a null value.
