A system, computer program product and method for a running process migration with planned minimized down-time. The method facilitates fast and efficient process migration by performing background data synchronization prior to actual process migration. The service slowdown is reduced by employing two-stage transfer method. During a first stage the service, being executed on the original machine, does not stop and all the available data required by this process is being copied. After the first stage is completed the service continues to be executed without an interruption, while the most of the data associated with the service process is already transferred to the new machine. During the second stage the execution of the service on the first machine is stopped. The files, which were not available during the first stage, are now copied. Then the execution of service is started on the second machine. The down-time is reduced to the duration of the second stage.

Techniques are provided to use historic execution state information to visualize tracepoint data. For example, historic execution state information corresponding to an application's previous execution is accessed. This historic execution state information was collected while the application was executing. After correlating the historic execution state information to the application's code, a tracepoint is associated with a portion of the code. Consequently, when the code is replayed based on the historic execution state information, the tracepoint causes a behavior of that code portion to be logged while the code is replayed uninterrupted. The code is then actually replayed based on the historic execution state information. During the replay, the tracepoint causes the behavior of the code portion to be logged. The logged behavior is visualized on a user interface.
