Hi, I have a problem with renaming resources with aliases. I've read both articles: https://www.pulumi.com/blog/refactoring-iac/ https://www.pulumi.com/docs/intro/concepts/resources/#aliases But I'm not sure how to apply it for my use case and prevent deleting resources After creating several component resources and deploying them I noticed that the parent-child relationship is not correct due to the bug in my code where I merged the

opts

from

parent

into

child

- but

parent_opts

overridden

child_opts

but I wanted it the other way around where I can override

parent_opts

with

child_opts

during the merge. For that, I created a sample code: https://gist.github.com/1oglop1/dcb258471cd33f572bedf67c63b7fe00 with 2 merging methods: -

merge_opts_a

-

child_opts.merge(parent_opts)

- current & wrong -

merge_opts_b

-

ResourceOptions.merge(parent_opts, child_opts)

- expected & correct When I change from

merge_opts_a

to

merge_opts_b

and run

pulumi preview

it says that I'll delete some resources which I need to prevent. How can I correctly apply aliases to prevent the deletion of the resources? Assume all components are supposed to be reusable in another project that does not suffer the current problem. How is this going to behave when I deploy a different stack with Aliases? Can the same alias be assigned to multiple components/resources? Is it possible to pass the alias from the parent without modifying the children's code? Thank you Attached pictures: left - current & wrong, right - expected & correct After trial and error, I managed to solve it by editing the

AppComponent

merged_opts = pulumi.ResourceOptions.merge(
            parent_opts,
            pulumi.ResourceOptions(
                parent=self,
                aliases=[
                    Alias(parent=self),
                    Alias(parent=pulumi.ROOT_STACK_RESOURCE)
                ]
            ),
        )
