A method and system for migrating source data from one or more databases to a destination database, wherein the destination database is selected based on power consumption of the destination database. A data migration server determines which destination database should be selected by selecting a number of candidates and comparing the power consumed, the available space and the maximum monthly power consumption limit. A user intervention policy is created to evaluate which data should be moved to a destination database. A “payback period” is calculated to determine the amount of time that will elapse before savings are realized.
