To move a CF structure instance from one CF to another CF:

1. Ensure the structure has another CF in its preference list - the structure may only be allocated in coupling facilities that are in its preference list. If necessary, create a new CFRM policy (or update an existing CFRM policy) to add the target CF to the preference list for the structure that is to be moved. See Planning a coupling facility policy for more information.

   It might also be necessary or desirable to remove the CF in which the structure is currently allocated from the structure's preference list, particularly for the case where the structure does not support rebuild. Note that it is generally recommended that a structure always have at least two coupling facilities in its preference list.

   Activate the new/updated CFRM policy using the SETXCF START,POLICY,TYPE=CFRM,POLNAME=polname system command.

   The policy change of the structure preference list might become pending until the structure is moved to another CF in the next step.

2. Use the instructions in Actions to remove a structure from a coupling facility to move the structure instance from one CF to another.

   Verify an update to the structure preference list in the CFRM active policy with the DISPLAY XCF,STRUCTURE,STRNAME=strname system command.

   If the structure is no longer in use (that is, the structure was deleted), use of the structure can be re-initiated once the preference list in the CFRM active policy is updated to remove the CF.

Verify the CF in which the structure is allocated with the DISPLAY XCF,STRUCTURE,STRNAME=strname system command.
