So I need to see essentially take a smaller database from another department and see which of them are on our Tessitura. Any tips on how to do this without having to search one-by-one? My best idea so far is to make an import file and run Constituent Import in "Review Mode", then look for duplicates. Has anyone got a better way? We're not necessarily going to import those we don't have - the other department just want to see the crossover.
