I guess I didn't explain this very clearly: There is one SQL database containing separate tables for history and active data. The data has always been separate since we started keeping history in 2.x tables back in the early 1990s. There is no business reason to combine them now, and lots of very good reasons to keep them separate. I don't want to re-write the entire application, only the monthly close. I actually thought there would be several options but maybe not...
