Hello again - is there a way to automatically transfer my taxonomy values from taxonomy-advanced back to taxonomy without manually adding the data back in?
(my search and filter does not work with the taxonomy_advanced' as uses wp's default)
There is no option to transfer the field value taxonomy_advanced to taxonomy. They saved data in different tables (wp_postmeta and wp_term_relationships) so you need to use custom code to do that.
You can create a service request here https://metabox.io/contact/, our developer will help you to transfer the field value for a small fee.
I spent the whole of yesterday manually migrating, and so pleased there wasn't an instant way that I missed. But the service request would have been great - Great to know that exists for next time!
