How to enable property again or transfer booking into same one but another listing

Hi there, 

For some reason my property 9766316Luxury Apartment - East Sarajevo  25 Spasovdanska, LukavicaClosed/Not bookable any more: link: https://www.booking.com/hotel/ba/luxury-apartment-east-sarajevo-lukavica.html?lang=xu

I created another property listing for the same property: https://www.booking.com/hotel/ba/luxury-apartment-east-sarajevo.html?lang=xu

It is the same property, just 2 different  listings. 

On first listening there is booking from 12 June to 12 Aug, can i transfer the booking into my second listening ?

Can you help me to do so.

Of if this is not possible can i enable first listing again so that i do not loose booking for that period. 

Thank you  and Best Regards,
