<p>A method of modeling a prospective database migration between database systems may include collecting performance data associated with a plurality databases in a first database system. The method may also include receiving a selection of a set of databases in the plurality of databases to migrate to a second database system. The method may additionally include computing, using at least some of the performance data, combined performance data that estimates how the set of databases will perform on the second database system. The method may further include providing one or more indications as to whether the set of databases should be migrated to the second database system. In some embodiments, the one or more indications may be based on the combined performance data.</p>
