How can I create a rule that passes cards between boards?

[Manuel Pastor Tomás]

I would like to create a rule type automation that does the following: when I create a card with label 1 on board A, it creates a copy on board B with label 2. Is that possible?

[DiMaggio Tucci]

Yes. Here's an example automation rule:

when a card in list "Repeat" with the green label is added to the board, copy the card to the top of list "Items" on board "Clone", remove the green label from the card, and add the red label to the card

You can do this under the "Rules" section of automations.

Keep in mind, the second card is a copy but it is a completely separate card.

There is a new "mirroring" feature being added this week if you want any changes to one card to sync to the other card after the copy is made, but I think the cards would have to have the same label. I haven't gotten to try the new mirroring feature, though.
