A resource requirements method and system is provided. The method includes identifying dependencies and calculating a utilization value for a source server. The source server is mapped to an application and a source infrastructure is compared to a target infrastructure. Deficiencies and differences associated with the target infrastructure are determined and dependency requirements for fulfillment in the target infrastructure are generated. The utilization value is compared to a resource capability of the target server and resource requirements for fulfillment on the target server are generated.
