Computer system model generation with tracking of actual computer system configuration

The present invention provides a system and method for generating models of a computer system. The method involves generating an original model of a computer system in an original configuration, and performing an original series of changes of the original model to yield an intermediate model. The original series of changes is recorded. The method further involves tracking the actual configuration of the computer system so as to detect a revised configuration of the computer system. Then, a resultant model is generated that corresponds to the computer system in a potential resultant system configuration that would result from a series of reconfigurations corresponding to said original series of changes or a revision thereof being applied to the system in its revised configuration rather than in its original configuration.
