Abstract
Just-in-time data migration in a live system is provided. Changes in a subscription that include structure, syntax, semantic, and identifier changes in data corresponding to the subscription are indicted to a new target system. A request to run an operation corresponding to the subscription on the new target system is received from a client device user. It is determined whether the operation needs related subscription data from a legacy system. In response to determining that the operation does need the related subscription data from the legacy system, the related subscription data for the operation is transformed just-in-time to support just-in-time migration of the related subscription data from the legacy system to the new target system. The operation is run on the new target system generating a new identifier for the subscription while referencing the related subscription data being migrated just-in-time from the legacy system.
