A method, system, and non-transitory computer readable medium for safely and efficiently migrating applications from one application server to another is provided. A termination request is received. When an API call has been sent by a first application since a last recurring checkpoint, the sent API call is processed one of several ways. Sometimes the API call is immediately terminated. Alternatively, the first application server waits a waiting period for an answer to the API call, and during the waiting period any new API calls are captured and not sent. Upon completion of the waiting period, if no answer has been returned, the API call is terminated. Then a new checkpoint of the application is taken in order to obtain a new checkpoint data set. The application is then migrated to another application server using the new checkpoint data set.
