Let's say that you use pulumi to provision a set of resources that should be "stable". If you later on would like to wrap those resources in a ComponentResource where the ComponentResource becomes the parent, is it possible to do so without deleting the set of resources and re-create them? What I would like to happen is that everything would remain the same and the resources just gets marked with a new parent, as long as they have the same name... but maybe that is the case?

hmmm maybe you need to import them from within your new component resource? It's a bit weird when they're coming from the same stack though I suspect at some point in that transition they will be flagged for deletion because the dependency tree will have changed

exactly, and that is my question. Is it possible to make that type of change without the deletion?

Well the parent property is just an URN, right? You could manually modify the state file and just update the parent property of those resources. But short of that I don't think there is a clean way to do this.

That was what I was thinking as well @bored-oyster-3147, but it feels like that approach is quite sensitive to errors.

Or you could make a second stack, and start with your component resource, and import the resources from the original stack into the new stack under the component resource

that was also an approach that crossed my mind... No need to do it now, but I see that might be something I want to do down the road.
