We recently switched to the Customer Hub and started looking into the Favorites functionality.

Previously, we used the Swish Wishlist app with a sync to Klaviyo, so I still have wishlist items (product IDs) saved in custom data.

I tried importing those IDs into the customer_hub_favorites field, but they don’t show up on the users’ Favorites list.

I’m not even sure if this kind of migration is possible — has anyone tried something similar or knows if it can be done?
