Hmmm, I’ve giving something like this much thought…
As long as there is a one to one relationship to the data you collected with GF to the fields that are supported by Connections you can use the CSV Import. So, I would do that and install Link. Now the next time one of your users log in, their user account will be linked to the their Connections entry allowing them to edit. so this would not require deleting the existing users at all.
Hope that makes sense and helps.
