# Free migration planning call with Tom Krones

> For hosts already on another platform such as Hostaway, Guesty or Hospitable. I'll migrate you myself, free. You don't have to disconnect anything first. I connect Host Tools to your Airbnb account alongside the software you're running now, and your listings come in switched off, so nothing touches your calendar or your guests until you turn one on. You stay live where you are until you're ready to move. Not on any software yet? Start with the getting started guide.
