1. An article of manufacture implementing code, wherein the code is executed to communicate with a database, source system and target system and cause operations to be performed, the operations comprising: querying a source system to determine configuration settings in the source system; querying a target system to determine configuration settings in the target system; providing a user interface to enable a user to enter configuration settings for the source system and target system to supplement the source system and target system configuration settings determined by querying the source system and the target system, wherein the configuration settings for the source and target configuration settings provided by the user via the user interface were not determined by performing the querying of the source system and the target system; combining the determined configuration settings from the source and target systems and the user entered configuration settings for the source and the target systems into a data structure in the database; accessing and processing the determined and user entered configuration settings for the source and target systems in the data structure to generate commands to configure the target system to implement the configuration settings in the data structure for the source system and the target system; and executing the generated commands to configure the target system.
