The information in this article is relevant only for the Vrbo full sync connection type.
It is not possible to move a Vrbo listing to a different Vrbo account, or to merge accounts together. As a workaround, you can publish listings via Guesty to the relevant Vrbo account, and new listings will be created in the account. Once done, contact Vrbo's Support team to move the listings' reviews from the previous account to the listings in the other account.
Keep in mind, each connected account in the Distribution section of Guesty represents a separate Vrbo account, so be sure to publish the listings to the correct account.
