Upgrade existing stack from serverless 0.5.x to 1.x (keeping same stack name)

[r.opper]

I am able to set the stack name in serverless.yml to match that of the serverless 0.5.x stack, but I still can’t update it because of the following error:

Resource ServerlessDeploymentBucket does not exist for stack xxx

I understand that the deploymentbucket is a new thing, but how can I create one for an existing stack from serverless 0.5?

[buggy]

Have you tried setting the deploymentBucket in your profile?
