I'm going to try out https://pulumi-community.slack.com/archives/C84L4E3N1/p1627030059344400?thread_ts=1626968113.333400&cid=C84L4E3N1 and report back

We do have

pulumi stack rename

, though 🤔 I haven’t used it yet, but it looks like you can pass it a fully-qualified stack name, so like

pulumi stack rename some-org/new-project-name/stack-name

Yeah, that does seem to work. Let me see if I can dig up some documentation for it.

You’d need to rename your stacks one at a time, if you have multiple stacks in a given project, and then change the project name in

Pulumi.yaml

when you’re done renaming all of them, but otherwise, resources all seem to come across into the new stack. (I’m using the Service backend, but I’d assume it’s the same with other backends as well.)

Ah, notably:

You can also rename the stack’s project by passing a fully-qualified stack name as well.

One thing is that you do need to change the name of the project in

Pulumi.yaml

after all of the stacks in that project have been renamed. Otherwise, your next Pulumi up will try to find a project by the old name and not find it (as it’s now got the new name).
