Method for transferring a computer system from a first phase (I) to a second phase (II), the computer system having a plurality of components, one of them being a coordinator; the first phase (I) being defined by a first rule set for a first implementation of the computer system;
the second phase (II) being defined by a second rule set for a second implementation of the computer system;
during the first phase (I) the coordinator being arranged for prescribing the first rule set to the plurality of components according to a first coordination scheme;
during the second phase (II) the coordinator being arranged for prescribing the second rule set to the plurality of components according to a second coordination scheme; wherein the coordinator is arranged to execute the following for transferring the computer system from the first phase (I) to the second phase (II):
a) loading a migration rule set comprising a first migration rules part (A) and a second migration rules part (B);
b) adjusting the first coordination scheme of the coordinator based on the first migration rules part (A) into the second coordination scheme, and
c) gradually transferring the other components to the second phase (II) based on the second migration rules part (B).
