Moving a Guest To Another Unit

How do I move a guest to a different apartment and unblock the days of the apartment he moved out of?

We had a pipe freeze in Apartment 5 two days ago and moved our guest to Apartment 4.   The guest is thrilled because he got an apartment twice the size for a month.  

However now I have 2 apartments blocked for nearly 30 day each.

Airbnb said if they change it it won't stick because of Ownerrez.

So I tried going in and changing the booking in here and got this message:

"Channel Calendar Linked

This booking is managed by the ________________ Airbnb channel so only check in/out time can be changed in OwnerRez.

If you need to change dates or property, we recommend making any changes on the channel which will then automatically update the OwnerRez booking. Or you can unlink from the channel calendar and make the changes in OwnerRez, but they won't be reflected on the channel."

I'm brand new here... still in the trial period. No idea how to unlink.  Can someone walk me through? 

In general you’d want to change the booking on Airbnb via the right hand side bar where it says change booking.

Are you saying you’ve tried that and get the warning message you posted?

Hi Adria, thank you for responding!

I clicked on his booking here: 

https://app.ownerrez.com/bookings?view=list

Then clicked on "Change/Move" button in the middle of the nav bar here:

https://app.ownerrez.com/bookings/9650018

Which sends me here to Change Booking : https://app.ownerrez.com/bookings/9650018/edit  

Where I get the warning from last night: 

• Channel Calendar Linked
• This booking is managed by the _________________________ Airbnb channel so only check in/out time can be changed in OwnerRez.
• If you need to change dates or property, we recommend making any changes on the channel which will then automatically update the OwnerRez booking. Or you can unlink from the channel calendar and make the changes in OwnerRez, but they won't be reflected on the channel.

There is an "unlink from channel" button which I didn't notice last night because I clicked on the Airbnb link in the warning.

I clicked the button just now  and got a pop-up warning which bothers me because it says it can't be undone.  

• Are you sure you want to unlink this booking from the channel calendar?
• This action cannot be undone.
• Channel calendar linked (the current mode) means OwnerRez will automatically update calendar changes from the Airbnb channel for this booking.
• If you unlink the calendars, you'll be responsible for making any changes yourself. No other bookings will be affected.

So I guess I can go ahead and unlink, change the property in Ownerrez and then call Airbnb to change it on their end?  

If I unlink will that apartment's calendar be forever unlinked, or just this booking?  

Normally, you should change the property in Airbnb.com and let that change sync to OwnerRez.
