How do I filter old issues off a Kanban board?

[Gabi Sehdou]

I am trying to adjust the current workflow in an active sprint. My question is: how I can undo the changes?

If the issues are Done - just do a Release to clear them from your board. 

If you just want to temporarily hide them, then create a Quick Filter under Board settings.

@Gabi Sehdou, the title does not seem to align with your question. Can you please restate what you are trying to do?

filter old issues: what conditions define the old issues? Do you mean status = Done and > x-days in that status or something else?

workflow changes: if you edited the workflow and wish to revert to the previous version then if you saved a copy when publishing your changes then simply associate the old version. If you didn’t save a copy then you will need to edit the active WF back to the original using your memory.
