You may purchase your full import at any time via your import page. 

The full import is started after we receive payment. If you'd rather schedule your import, please contact us before purchase to schedule the time and date. 

We always remove the sample import data before proceeding with the full import. The full import starts from scratch with all of the current data in your source database. 

If you need to redirect your import to a new instance of your database (i.e. if you are changing from a sandbox to your production database) - simply send us a message and we can help you reconnect.
