I am not quite sure how to explain this but here goes...

I have an entire database (400,000 records) entered using the Recorder 3.3 checklist.  The database is now in R2002.  I need to extract all the birds and plants - could I use the BIRDS and VASCULAR PLANTS checklists, or would this somehow prevent some of the relevant records from being extracted, if the species names have changed from one checklist to another?
