Looking for simple Deleting Lists workaround

[PeterD]

In the Trello documentation, it is mentioned that lists and cards cannot be deleted:
Deletion is permanent in Trello and in an effort to prevent accidental deletions we do not have an option to delete a list on the original board. 
On the other hand, it is quite easy to delete a complete board, accidental or not. (?)
So the only workaround to delete a list is to move it to another board and delete this board.

Tedious in my case: I have a board with 60+ guests, with two lists per day for tasks. At the end of the month, the users remove the lists by archiving it - deleting is not possible-. So I now have a board hitting the limit of 2.850 lists (archived and active)

The users now cannot create new lists, according to the Trello workaround, I now have to move all the archived lists back to active and move them to another board. Doing this a few thousand times is not why I got into this business.

Only solution: duplicate the board, only active lists are copied.
But I still have to find a way to direct the 60+ guests to this new board.

Is there no scripting solution to delete my 2.800+ archived lists?

Hi Peter, 

Unfortunately, you mentioned all the options, there isn't a native feature to bulk delete lists, 

We don't have visibility on third-party Power-ups, so you may find one that suits your needs. 

In the future you can create an automation, such as scheduled automation to move all the cards from the lists you usually archive to a different board, then you can delete the backup board or just rename it. The scheduled automation would be also able to move the list to a different board.

Right now, you would need to copy the board as you mentioned and worked on the new one, inviting all your users once more, or you can unarchive the lists and transfer it to a different board. 

Let us know how it goes
