You archive Initiatives just like you archive cards in the Cards Workflow.
First, move all completed Initiatives into the "Ready to Аrchive" column.
The system keeps your Initiatives there for a certain period of time (1/7/14/30 days).
The default setting is 7 days. After that time period expires, the cards will be automatically moved to the Permanent Archive.
Important: The Initiatives in the Permanent archive are zipped up and they can be restored anytime if needed. For more information, please check the dedicated article.
