You can move a policy from one circle to another through a Governance Meeting of the supercircle that both circles belong to.  (Premium users can also use Asynchronous Governance Proposals to do the same thing.)


In the following example, Tree is the supercircle, and Poplar and Yew are the subcircles.  We are moving a policy from Poplar to Yew.


First, you will need an agenda item to move the policy out of the first circle.


Restructure the Sub-Circle that has the policy, as shown below:



After you accept that proposal, you will need an agenda item to move the policy into the second circle, as shown below:



After you accept that proposal, the policy will have moved from Poplar to Yew.
