<https://www.pulumi.com/docs/reference/cli/pulumi_stack_rename/>

&gt; You can also rename the stack’s project by passing a fully-qualified stack name as well. For example: ‘robot-co/new-project-name/production’.
This assumes you're using the Pulumi Service backend.

I am not using Pulumi Service backend, will the rename cli still works for me?

Then you should just be able to change the project name in `Pulumi.yaml`.

if I do that, everything marked as need to recreate right?

If you have existing resources, then yes. You can stop the replacement of these resources by using aliases. <https://www.pulumi.com/docs/intro/concepts/resources/options/aliases/>

Basically, aliases are a one-time operation to tell Pulumi a resource URN has changed, but you'd like to keep the existing physical resources.
