Yes we have had other companies migrate from GoDaddy. Below are the known limitations of this due to this being an IMAP configuration.
Non-delivery reports migrated to exchange will not be as complete as if we they would be if they were sent from exchange based client. For instance, a non-delivery report migrated from IMAP server cannot be resent by opening it and selecting Resend in Outlook.
If an IMAP source has sent mail in a folder other than “sent items,” the target will have mail migrated to a folder of an identical name and not to the “sent items” folder in Exchange/Office 365. The user can move the mail from one folder to another after migration.
The Follow Up flag is not migrated.
