Migrate Datasmith imported asset

Do someone know how to migrate datasmith asset from one project to another :
In my case, it is a 3dmodel of a furniture with 1 parent actor and 3 staticmesh children. I can’t migrate the parent (an empty actor). I can’t either copy-paste between level. I can migrate the folder with mesh/material/texture, but I loose then parent actor, with his right furniture name…
Does anyone know the right process for this please ?
