It is not possible to import Trello cards into Productboard or sync existing features to existing cards.2-way sync of fields like name & description is not yet supported.Note that every card in Trello will have a link back to Productboard in the description and you can also click on the Trello task column in Productboard to open up the associated card in Trello. You can always deactivate the integration or simply delete the task column. All features and subfeatures must be pushed individually. Note: Pushing a Productboard subfeature into Trello creates a new card just as it would for a feature. (Or find this same button in the feature's details side pane.) On your board, find the feature you'd like to push to Trello and click Push in the Trello task column.Toggle on these special Trello task columns and the whole task column group if it isn't already displayed.
