1. A migration method for migrating a virtualized function installed on a first server in a data center of a communication architecture, implemented in an administration entity for administering said first server, said administration entity being able to transmit, to a management entity for managing the virtualized function, data relating to installation of the virtualized function, the method comprising at least:
receiving a notification message comprising at least one item of data of a technical environment parameter relating to the first server;
determining an action to safeguard the virtualized function if the at least one item of data crosses a predefined threshold, the action to safeguard the virtualized function being determined by identifying the virtualized function on the impacted first server using a correspondence table comprising a list of virtualized functions installed on at least the first server; and
sending, to the management entity, a message to migrate the virtualized function to a second server selected as being not impacted by the at least one item of data of the technical environment parameter.
