https://community.appian.com/discussions/f/general/20746/can-i-get-old-task-backHi 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?en-USTelligent Community 12https://community.appian.com/thread/80830?ContentTypeID=1Thu, 08 Apr 2021 18:20:54 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:39a5a31b-a6a6-494d-a280-7d1296721cbaChris<p>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)?&nbsp;&nbsp;</p> <p>You can revert versions of your interface (and other objects) in /design by selecting the checkbox next to the object, choosing the &quot;More&quot; dropdown, select Versions, open a prior version and Save to reinstate it.&nbsp; You can delete versions, but we typically re-save a prior version instead to retain all version history.&nbsp; 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.&nbsp;&nbsp;</p> <p><a href="https://docs.appian.com/suite/help/21.1/Managing_Object_Versions.html#revert-to-a-previous-version">docs.appian.com/.../Managing_Object_Versions.html</a></p><div style="clear:both;"></div>
