1. A method for performing a status change on at least one computer, wherein the computer is a computer within a cluster, from an actual condition to a target condition, the status change relating to one of replacement and initial operation of software, the method comprising the steps of:
- subdividing the method into a preparation phase and a subsequent active phase, wherein the preparation phase is executed during operation of the actual condition and the status change is effected during the active phase, wherein the preparation phase includes;
registering control information relating to the target condition;
automatically generating at least one script from the control information; and
saving data for the target condition to a cache directory;
and wherein the active phase includes;
terminating operation in the actual condition; and
applying the script via which the data for the target condition is relocated from the cache directory to a destination directory, wherein execution of the script is time-optimized.

14. A computer-readable storage medium having a program incorporating software code portions for performing, upon execution by a processor, a status change on at least one computer, wherein the at least one computer is a computer within a cluster, from an actual condition to a target condition, the status change relating to one of replacement and initial operation of software, with the program being subdivided into a preparation phase and a subsequent active phase, the software code portions comprising:
-
registering in the preparation phase and during the operation of the actual condition, control information relating to the target condition; automatically generating, in the preparation phase, and during the actual condition, at least one script from the control information; saving, in the preparation phase and during the actual condition, data for the target condition to a cache directory; terminating, during the active phase, operation in the actual condition; and applying, during the active phase, the script via which the data for the target condition is relocated from the cache directory to a destination directory, wherein execution of the script is time-optimized.
