Cancels the current workspace subscription for the given domain(s) and provisions a new subscription for the same domain. Mailboxes and OAuth-related configuration are preserved; the flow runs asynchronously after this call returns.When to use: Typically when a customer opts out of “one plus year” pricing and you need a fresh subscription at standard rates (see product docs for pricing implications).What this does not do: It does not accept purchase dates, renewal dates, or prewarmup flags. Target subscriptions only by subscriptionIds or domainNames.Prewarmup: Subscriptions with prewarmup mailboxes cannot be recreated; the API returns 400.
