provided are techniques for verifying application compatibility , comprising providing a configuration knowledge server to store information about configuration issues ; detecting , by a configuration checking agent , a reconfiguration of a computing system ; signaling , by the cca , a configuration checking service , in response to the detecting ; in response to the signaling , requesting , by the ccs , a compatibility report , from the cks , about potential configuration issues with respect to the reconfiguration ; transmitting the compatibility report from the cks to the ccs ; parsing , by the ccs , the compatibility report to identify a compatibility issue with respect to the reconfiguration ; and in response to identifying the compatibility issue , dynamically performing an action to mitigate the compatibility issue .
