What’s the typical way of renaming a resource? Specifically, let’s say I have:

appsv1.NewDeployment(ctx, "myDeployment", &appsv1.DeploymentArgs{

and I want to change it to

appsv1.NewDeployment(ctx, "my-deployment", &appsv1.DeploymentArgs{

If I do that, it fails because it says the Deployment already exists with that name (note that I have given it an explicit name, so it is not using autonaming)

You should be able to set the

DeleteBeforeReplace

resource option to do this: https://pkg.go.dev/github.com/pulumi/pulumi/sdk/v3/go/pulumi#DeleteBeforeReplace

Would you recommend to set it once to do this replacement and then remove it? Because generally I wouldn’t want this behavior, it’s just this one time as I do the renaming.

Yes.

Conceptually I just want something like a pulumi stack rename resource <old name> <new name>

As far as I know, there’s no current support for this.
