oh thank goodness. that made it very easy once i figured out how to export the tables properly. i exported each _events_ table individually via phpmyadmin, then imported each table into the development server, after i had dropped the same-named tables. now that they were all imported EE is working as expected and with up to date information for all of our events. i won’t switch to EE4 if data migration is not a simple-ish process like this was.
