Hi i have been testing converting over from xenforo to IPS and i have notices that although my account content has converted the joined date is the day of conversion rather than the actually join date which was something like 2010. 

If an account is merged into another one, due to having the same email address, then the content will be associated with the already existing account. None of the account information will be adjusted as a result of this merge.

So when I do the final migration what's the best way to do this. Use a different email address in the original IPS admin account?
