This paper proposes a mechanism of services migration in the background of the operation management of large enterprises using the notion of "security baseline". It splits the original migration into two parts. First, transport the environment on the server, which includes the custom, transform, distribution and deploy of baselines, and then the running services. By this way, the preconditions of the businesses and the services will not be omitted and the environment is guaranteed. Furthermore, it is of convenience that one can control multiple servers from one terminal. Finally, this paper introduces the realized system and the baseline transform algorithm in detail. The experiment result shows that the mechanism is high efficient and satisfactory.
