There are a few rules to consider when moving OUs.
First, you can only move an OU to a new destination beneath its existing top-level OU; Child OUs cannot be moved below a different top-level OU, however a top-level OU can be made a Child OU of any OU that is not it's own descendant.
Second, all projects and financials attached to the OU will move with the OU to the new destination. The moved OU will gain all the inherited cloud rules from the new parent OU; the inherited cloud rules from the previous parent OU will no longer apply.
Any operation that requires moving projects to a different OU tree should be done via a project move rather than an OU move.
To move an OU:
- In the left navigation menu, click OUs >All OUs.
- Click the ellipsis menu next to the OU and select Move OU.
- Select the new parent OU as your destination OU.
- Click Move.
