Hi,
FeatureClassToGeodatabase and FeatureClassToFeatureClass tools do not copy domains definition. I tried with ArcGIS Pro 2.7 or 2.8. It was working in ArcGIS Pro 2.5.
I tried with ArcGIS Desktop 10.8 and domains are correctly copied.
I cannot find any parameters or options to specifiy if domains should be copied with these tools.
Is this a bug in the new versions of ArcGIS Pro ?
Any help would be appreciated.

Looks like it should work with FeatureclassToFeatureclass given the restrictions listed in the help topic
Have you enabled the Transfer field domain descriptions (Environment setting) ?

After further tests, FeatureClassToFeatureClass tool works with domains. It is only the FeatureClassToGeodatabase that does not transfer domains information.
