A method, system and article of manufacture for migration of databases and, more particularly, for optimizing migration of a database from a source system to a target system. One embodiment provides a computer-implemented method for optimizing migration of a database from a source system to a target system. The method comprises collecting source parameters related to performance characteristics for the database on the source system. On the basis of the collected source parameters and target parameters of the target system database configuration information is generated. The target parameters will affect the operation of the database on the target system as compared to the operation of the database on the source system. The database configuration information is applicable to tune the database to operate on the target system. The method further comprises configuring the database to run on the target system according to the database configuration information.
