I recently renamed my org and I'm getting a lot of errors like this from stack references when trying to refresh. Is there any better way to remediate it than to edit the stack state or bring everything down and back up again?

Does this stack & the one it is referring are in the same org?

Yes

From the error it seems as if the stacks are still not part of the org, maybe you can try a pulumi up/refresh on the stacks which are being referred here first

Unfortunately that didn't work. The only thing that seems to work is deleting the stack ref from the stack state

Yes that would work but if this ref is coming from the code then won't it come back again if you run pulumi up/preview?

Sorry yeah I failed to replace all the names but those projects were in the same org. Refreshing failed because the stack with the old org name wasn't found but once I deleted it from the state it worked.
