The common migration event came across as multiple immigration events - one
per person. The fact that 5 people experienced the same event was lost except
if you looked at the date and notes. I am currently in the process of post
conversion clean-up.

Many current apps allow sharing of events, however the GEDCOM  standard does not allow that. Hence on export, apps will duplicate the events.
