We have a Temporal instance that is heavily used but severely out of date version-wise. We want to move to the Temporal Cloud or set up another upgraded Temporal instance. Is there a recommendation or best practice on how to point to the new Temporal instance while also remaining connected to the old Temporal instance so that workflows in a retry state will be able to complete?
As an example, in case this is not clear, we might have workflows that deliver data to customers but their servers are not receiving at the moment so we will retry for 4 days to send the data. If we point to a new Temporal server, how will these workflows that are being retried complete? Thank you.
