Can I get old task back?

Hi Team, 

By mistake, I imported the wrong Appian package as an update to an existing one, Is there any way to get the old open task back?

  • Just to clarify, is this situation where you imported a new version of the SAIL interface which is being referenced in legacy running process instances (started prior to your update)?  

    You can revert versions of your interface (and other objects) in /design by selecting the checkbox next to the object, choosing the "More" dropdown, select Versions, open a prior version and Save to reinstate it.  You can delete versions, but we typically re-save a prior version instead to retain all version history.  Note if you imported changes to objects that are referenced by the interface, these will have to be considered as well as you may encounter unexpected behavior otherwise.
