Hi Jonathan - Unfortunatly there is not a direct 'easy' way for changing all previously mapped content that was mapped somewhere else to being mapped into another profile field or user credential. Basically all data is saved in the DynamicRegistration_QuestionResponse table but then after that its based on where the fields is mapped with DNN.
The only way to really handle this is to write up some SQL queries to find the old data in either our tables or in the DNN Core (the other field where you mapped it) and then update the DNN users table based on that)
1st - Maybe there isn't a problem at all? I know you specified this in a new email profile field that is set under advanced question options, DNN Core field, but was it also set under the DNN Core Integration area? If it was set under the DNN Core Integration area as well then you should already have the data.
If you don't then you would need to do a few things....
1. Write a SQL Statement to update the Users table based on the previous User Profile Property Definition ID
OR
2. Write a SQL statement to update the users table based on the DynamicRegistratin_QuestionResponse table.
Your SQL statement might be slightly changed from some other customers that needed this because I believe this is the first time that a customer needed the main users table / user credentials updates. Sometimes customers have needed the user profile table itself updated.
I would check into this thread:
