I have a simple email with a few Dynamic Content Blocks all of them based on the Data Extension 'A'.
In a Journey, the entry source is the Data Extension 'B' (same structure, same fields than the Data Extension 'A') and the email includes the dynamic content blocks based on the Data Extension 'A'.
I would like to confirm that when the journey is activated, the Dynamic Content blocks of the email will still use the information of Data Extension 'A' instead of 'B'.
If yes, is there a way to change the source of the blocks without having to replicate all of them from scratch?
