When designing policy it is important to bear in mind the order in which the policy items are executed. Policy items are executed and are listed on the page in the following order:
1. DELETE USER
2. RENAME USER
3. ADD USER
4. JOIN GROUP
5. UNJOIN GROUP
6. SCRAMBLE USER
A RENAME occurs before a SCRAMBLE. If the requirement is to rename FredAdmin1 to BillAdmin1 and SCRAMBLE the account, then the SCRAMBLE action should be targeted at the BillAdmin1 account and not FredAdmin1.
