Even though you can start fresh with the Experiences app, sometimes you may want to import your bookings from your previous system. We advise you to be careful with that as you could end up notifying your customers from two different systems of their upcoming experiences unless your previous system doesn't do that.
We have not yet developed a way to automate the importing of pre-existing bookings you might have from another system. However, here is how we recommend that you do it:
Make your new experience Free and turn off the new order notifications for that experience
Go to the storefront for that experience and enter each one of your future bookings from the other system by hand (yes, I heard your big sigh and I understand). This way you don't have to enter credit card information but the customer gets assigned to the proper time slot and inventory is adjusted correctly.
Then you change the experience from Free to Pre-paid and turn the notifications back on.
At this point, all your previous bookings are now in the Experiences system and will be notified 24 hours before their scheduled time as well as be informed of changes to their booking.
If you need some help with this, please reach out to us and we can get you some low-cost help. After all, not everyone loves mind-numbing data entry.
