Hi Jeff Mah,
A major impact on the DB size might be moving the Media modules contents from DB to the filesystem - we have introduced the feature for
alternative file storage: file system for the Images, Videos, Documents & Files
Libraries in our Sitefinity 4.2 release.
Concerning content versions, you can access the version history data using VersionManager and delete the items programatically. Please take a look at this forum thread
where we have provided a sample on using the VersionManager and working with content version history.
If there's anything else you'd like to ask , please do not hesitate to get back to us.
