I want to do the same action in the "Asset definition Toolbar" menu switch between definition version via python.

I cant seem to find anything in the hou.hda, hou.HDADefinition, or houNodeType.

When I toggle between hda versions I can see houdini is temporarily creating a new node (as the unique node name increments) then renames it to the original node (I'm assuming its being destroyed)

Anyone know what is being called? a uitil or something?

it's a method of the Node class - changeNodeType()

terrible nom tested code

nd = hou.node('/obj/FlipsInNips1')
nd.changeNodeType("namespace::main::FlipsInNips::2.0")
