In a computer-implemented method for validating interoperability of installed components of a computer system, site data identifying the installed components of the computer system and a version of each of the installed components is received, component dependency data identifying at least one component of the installed components requiring installation of another component of the installed components is received and component interoperability data identifying versions of a component of the installed components that are interoperable with versions of another component of the installed components is received. A version dependency compatibility acyclic graph is generated based at least on the installed components, the component dependency data and component interoperability data. It is determined whether the installed components are interoperable based on the version dependency compatibility acyclic graph.
