    Well, replication throws a wrench in what I would consider unless it is something you could tear down and rebuild.

    Regarding the deletion of data my first question is to ask what is the ration of data being kept to data being deleted.  That alone will have an impact in how you approach the task.

    Agree with the question from Lynn. The ratio of data volume to remain TO the data volume to remove becomes crucial . It then helps to favour other options , like extracting the required data (if its significantly less than the data to remove) to a staging DB and then dropping this database altogether.
